(3) Potential difference = IR
(4) Electric resistance \(=\frac{V}{I}\)
(5) Current \(=\frac{V}{R}\)
(6) Resistivity \(=\frac{RA}{L}\)

Give scientific reasons:

Question 1.
Free electrons are required for conduction of electricity.
Answer:

  • Every atom of a metallic conductor has one or more outermost electrons which are very weakly bound to the nucleus.
  • These are called free electrons. These electrons can easily move from one part of a conductor to its other parts. The negative charge of the electrons also gets transferred as a result of this motion.
  • The free electrons in a conductor are the carriers of negative charge. Hence, free electrons are required for conduction of electricity.

Question 2.
Wood and glass are good insulators.
Answer:

  • Those substances which have infinitely high electrical resistance are called insulators.
  • Wood and glass have high resistance and negligible free electrons for conduction of electricity.
  • Hence, wood and glass are good insulators.

Question 3.
Connecting wires in a circuit are made of copper and aluminium.
Answer:

  • Copper and aluminum are good conductors of electricity.
  • They have low electrical resistance and large number of free electrons.
  • As they are malleable and ductile, they can be drawn into thin wires. Hence, connecting wires in a circuit are made of copper or aluminum.

Maharashtra Board Class 9 Science Solutions Chapter 3 Current Electricity

Question 4.
A thick wire has a low resistance.
Answer:

  • The resistance (R) of a wire is inversely proportional to the cross-sectional area (A) of a wire. i.e., R i
  • Thus, greater is the cross-sectional area of a conductor (wire), lower is its resistance. Hence, a thick wire has a low resistance.

Question 5.
A series combination of resistances is used to increase the resistance of a circuit.
Answer:

  • When resistances are connected in series, the effective resistance of the resistors is equal to the sum of their individual resistances. Rs = R1 + R2 ………….. Rn
  • The effective resistance is larger than each of the individual resistances. Hence, This arrangement is used to increase the resistance in a circuit.

Question 6.
A parallel combination of resistances decreases the effective resistance of the circuit.
Answer:

  • In a parallel combination, the inverse of the effective resistance is equal to the sum of the inverses of individual resistances. \(\frac{1}{\mathrm{R}_{\mathrm{p}}}=\frac{1}{\mathrm{R}_{1}}+\frac{1}{\mathrm{R}_{2}} \ldots \ldots \cdot \frac{1}{\mathrm{R}_{\mathrm{n}}}\)
  • The effective resistance of resistors connected in parallel is less than the individual resistors.
  • Due to this, any addition of an individual resistance in parallel combination will decrease the overall resistance of the circuit. Hence, a parallel combination of resistance decreases the effective resistance of the circuit.

Question 7.
Lightning occurs from sky to earth.
Answer:

  • Lightning is the electric discharge travelling from clouds at high potential to the earth’s surface, which is at zero potential.
  • The earth is always at lower potential as compared to the clouds.
  • Hence, lightning occurs from sky to earth.

Question 8.
In streetlights, bulbs are connected in parallel.
Answer:

  1. Even if any one of the several bulbs connected in parallel becomes non-functional because of some damage to its filament, the circuit does not break as the current flows through the other paths, and the rest of the bulbs light up.
  2. When several bulbs are connected in parallel, they emit the same amount of light as when they are connected individually in the circuit, while bulbs connected in series emit less light than when connected individually. Hence, streetlights are connected in parallel.

  • If a person gets an electric shock, you should not touch that person. You should switch off the main switch or remove the plug from the socket if possible.
  • If not, then you should use a wooden pole to push the person away from the electric wire.

Question 2.
In a domestic circuit colour code is followed while setting up electrical wiring.
Answer:

  • The electricity in our homes is brought through the main conducting cable either from the electric pole or from underground cables.
  • Usually, there are three wires in the cable.
    (a) Live wire which brings in the current. It has a red or brown insulation.
    (b) Neutral wire through which the current returns. It is blue or black.
    (c) Earth wire is of yellow or green colour. This is connected to a metal plate buried deep underground near the house and is for safety purposes.
  • In India, the voltage difference between the live and neutral wires is about 220 V.
  • Live and neutral wires are connected to the electric meter through a fuse.
  • They are connected through a main switch, to all the conducting wires inside the home so as to provide electricity to every room.
  • In each separate circuit, various electrical appliances are connected between the live and neutral wires.
  • The different appliances are connected in parallel and the potential difference across every appliance is the same.

Question 3.
Fuse used in electrical circuit can save electrical objects from damage.
Answer:

  • Fuse wire is used to protect domestic appliances.
  • It is made of a mixture of substances and has a specific melting point.
  • It is connected in series to the electric appliances. If for some reason, the current in the circuit increases excessively, the fuse wire gets heated and melts. Maharashtra Board Class 9 Science Solutions Chapter 3 Current Electricity
  • The circuit gets broken and the flow of current stops, thus protecting the appliance.
  • This wire is fitted in a groove in a body of porcelain-like non-conducting material. For domestic use, fuse wires with upper limits of 1 A, 2 A, 3 A, 4 A, 5 A and 10 A are used.

Question 4.
Bulbs arranged in parallel glow brighter than bulbs arranged in series.
Answer:

  • The amount of light given out by bulbs in parallel combination will be more than that in series combination.
  • In parallel combination the resistance of the overall circuit decreases whereas in series it increases, so the current flowing through the bulbs in parallel circuit is more.
  • Due to this, intensity of light given out by bulbs in parallel combination is more than the bulbs in series combination.

Complete the paragraph:

Question 1.
If resistors are connected in series,
Answer:
The same current flows through each resistor. The effective resistance of the resistors is equal to the sum of their individual resistances. The potential difference between the two extremes of the arrangement is equal to the sum of the potential differences across individual resistors. The effective resistance is larger than each of the individual resistances. This arrangement is used to increase the resistance in a circuit. This type of connection is used in electrical heating equipment like geysers, iron, and hair dryers.

Maharashtra Board Class 9 Science Solutions Chapter 3 Current Electricity

Question 2.
If a number of resistors are connected in parallel,
Answer:
The inverse of the effective resistance is equal to the sum of the inverses of individual resistances. The current flowing through an individual resistor is proportional to the r inverse of its resistance and the total current flowing through the circuit is the sum of the currents flowing through individual resistors. The potential difference across all r resistors is the same. The effective resistance of resistors connected in parallel is less than r the least resistance of individual resistors.

This arrangement is used to reduce the resistance in a circuit. Even if any one of the several bulbs connected in parallel becomes non-functional because of some damage to its filament, the circuit does not break as the current flows, through the other paths, and the rest of the bulbs light up. When several bulbs are connected in parallel, they emit the same amount of light as when they are connected individually in the circuit, while bulbs connected in series emit less light than when connected individually.

Read the passage and answer the questions.

Passage I

Issues of workers: The first textile mill was started in Mumbai on 11th July, 1851 by Kawasjee Dawar. Eventually, mills started in Dadar, Parel, Bhaykhala, Shivdi, Prabhadevi and Worli. This part came to be i known as Girangaon or ‘town of mills’. In the 1980s, the increasing unrest among workers was due to the economic conditions in other sectors. In some industries the wages of the workers were increasing. They were also getting more amounts as bonus. They were getting more facilities than the textile mill workers.
In the Diwali of 1981, the workers expected to get a bonus of 20%. The Rashtriya Mill Mazdoor Sangh, which was negotiating with the employers, agreed upon 8 to 17% bonus without taking the workers into confidence. The cut in the bonus proved to be the cause of unrest. Some workers went to Dr. Datta Samant. They asked him to accept their leadership, Workers of 65 mills came together and Dr. Datta Samant led the strike. On 18th January 1982, two and a half lakh workers went on strike. Girangaon mills stopped running making it seem like Mumbai’s heart topped throbbing.
The Chief Minister of Maharashtra, Barrister A. R. , Antulay set up a committee to solve this issue. Later Babasaheb Bhosale became the Chief Minister of Maharashtra State. He insisted that as per law, he would talk only with the Rashtriya Mill Mazdoor Sangha. Dr. Datta Samant demanded that the law be revoked. In the beginning, the striking workers received help from their native villages. It was also , not very difficult for them to help each other. They set up departmental committees and distributed food grains, assistance in the form of funds, etc. The left parties had supported the strike. As the strike , dragged on, efforts were made to split the striking workers’ ranks. Even as the strike completed 6 months, the central government completely ignored it. The workers started a Jail Bharo Agitation’. In , September 1982, one and a half lakh workers took a march on the Legislative Assembly of Maharashtra State. It didn’t help at all. The strike completed a year. This was the first strike to have gone on for a year. In this period, about one and a half lakh workers became unemployed. As polyester had come into greater demand than cotton cloth, the sale of mill , cloth had already got affected. The mills moved from Mumbai to Surat in Gujarat. The Central government nationalised 13 textile mills. Appointment of i arbitrators did not help to resolve the issue.

Question 1.
Name the worker’s union mentioned in the passage. Why were the workers agitated with it?
Answer:
(i) The worker’s organisation mentioned in the passage is Rashtriya Mill Mazdoor Sangh.
(ii) The workers were agitated because they received less bonus and facilities in their textile mills, whereas economic conditions in the other sectors of the economy were far better.
(iii) The Rashtriya Mill Mazdoor Sangh that negotiated with the employers, settled at 8 to 17% of bonus as against the expectation of 20% by the workers.
(iv) The cut in the bonus led to the workers agitation.

Question 2.

  • In recent decades, the use of technology and mechanisation has increased in agriculture.
  • Due to the mechanisation of agriculture, the surplus manpower employed in agriculture have become devoid of agricultural work.
  • This working class started coming to cities to look for work and as a result urban population started increasing.

(B) Trade
Answer:

  • When a place in a region is favourable in terms of transport, loading-unloading and storage of goods, it developes into a trade centre.
  • This leads to the growth of business complexes, banks, credit societies, godowns, cold storage, houses, etc.
  • For example, Nagpur’s central location has facilitated trade and hence urbanisation has also taken place here.

(C) Industrialisation
Answer:

  • Industrialisation leads to increase in the hopes of people who are attracted towards the industries from surrounding areas for employment.
  • Rapid growth of Mumbai in the 19th century was due to the textile mills which were started here.
  • Many fishing villages (Koliwadas) became part of Mumbai metropolitan2 area due to industrialisation and urbanisation.

Maharashtra Board Class 9 Geography Solutions Chapter 10 Urbanisation Human

(D) Amenities in urban areas
Answer:

  • Urbanisation leads to development of a number of amenities and facilities in urban areas.
  • Transportation, communication, educational facilities, medical facilities, fire brigade, various sources of entertainment, etc. are examples of amenities in urban areas.
  • A good transportation not only makes a journey easier but also has a positive effect on freight transport, development of markets, trade, etc.
  • Development of higher educational facilities in urban areas attract students from rural areas to urban areas. E.g. Pune.
  • Development of high quality medical facilities in urban areas bring many patients and their family members from different parts of India to these areas.

(E) Social harmony in the cities
Answer:

  • Social harmony refers to the exchange of cultural and social customs and traditions as people from different parts live together in the cities.
  • An increase in urbanisation leads to an increase in secondary, tertiary and quaternary occupation.
  • This results in an increase in employment opportunities due to which people from different parts of the country come to cities and there is an exchange of customs and traditions.

4. Compare the following and give examples:

(A) Transportation system and traffic jams
Answer:

  • As cities grow, people start living on the outskirts and in the suburbs of the city.
  • People commute to the centre of the city for businesses and industries, trade, jobs, education, etc.
  • Public transportation system is insufficient and hence the number of private vehicles increase.
  • This results in an increase in traffic jams and a lot of time is consumed in travelling from one place to another.
    e.g. Although Mumbai has a well developed transportation system it is insufficient to fulfil the growing needs of people.

Hence, traffic jams are a frequent site in different pockets of Mumbai.

(B) Industrialisation and air pollution
Answer:

  • Industrialisation refers to the growth in number of industries in a particular region.
  • As more and more industries crop up, it becomes convenient for the industries to violate the environmental laws.
  • Paucity of facilities, insensitivity towards environment are the other factors which leads to an increase in the pollution level.
  • Hence, Industrialisation and Air pollution are the two aspects of the same coin.
    e.g. Delhi, Faridabad and Varanasi are the ! victims of rapid industrialisation leading to j severe air pollution.

Maharashtra Board Class 9 Geography Solutions Chapter 10 Urbanisation Human

(C) Migration and slums
Answer:

  • The increase in the number of migratory people causes an increase in the slums.
  • Generally migration from rural to urban areas takes place in search of job opportunities, which are hard to find.
  • The housing facilities do not increase in the same proportion as the population, so the poor migrants can not afford the housing in the cities.
  • This encourages the migrants to build illegal temporary and semi-structured houses known as slums, in open spaces. e.g. Slums in Dharavi (Mumbai city)

(D) Amenities and increasing crime
Answer:

  • Amenities refers to facilities that provide comfort, convenience or pleasure to people.
  • Transportation, communication, educational and medical facilities, fire brigade, etc. are the examples of amenities available in urban areas.
  • Unemployed people who have migrated to the cities are unable to avail these amenities.
  • This leads to an increase in thefts, burglaries, scuffles5, murders, etc. which disturb the social harmony of the cities.
    e.g. Pick pocketing in the local trains.
