Question

3. Answer question numbers 3(a) - 3(d) on the basis of your
understanding of the following paragraph and the related studied
concepts.
India is the third largest electricity producer ahead of Russia and Japan.
India produced 1160. 10. billion units (BU) of electricity. One billion unit
is enough to power 10 million households. Out of total production of
electricity, only 53.7% of India's commercial energy demand is met through
the country's vast coal reserves and rest is from other sources of energy,
India is endowed with economically exploitable and viable hydro and solar
energy to generate electricity. In India the voltage is fixed at 220 volt 50
bert. If you want to determine the value of current flowing at any time, it
an be roughly estimated from the rating given on each appliance connected
in the circuit.
3(a) Give two limitations of thermal power plant.
2/1
3 b .In household electric circuit, different appliances are connected
parallel to one another to get the:
(i) same voltage
(i) high voltage
(iv) None of these
(iii) low voltage
3c) Write one difference between electric energy and electric power
3(d) Name two power plants based on renewable source of energy.​

Answer 1

Answer:

a) thermal power plant exploits non renewable resources on a large scale.

it causes pollution.

b)same voltage

c)Electrical power is the rate of amount of electrical energy transferred. Electrical energy is the energy generated as the result of the potential difference in a circuit which causes current to flow through it.

one more difference is that energy is measured in joules and power is measured in unit(KwH)

d)Solar power plant,hydro power plant.
