Q-1 What is power? How do you differentiate
wer? How do you differentiate kilowatt from kilowatt hours? The Jog falls in
state are nearly 20m high. 2000 tonnes of water falls from it in a minutes. Calculate
equivalent power if all this energy can be utilized?

Answer 1

Answer:

Power is the rate of doing work. Kilowatt is the unit of power and kilowatt hour is the unit of energy.

h = 20 m, and mass = 2000 × 103 kg = 2 × 106 kg

Power = m g h / t = 2 x 106 x 10 x 20 /60 w

= 4 / 6 x107w

= 2 / 3 x 107w

Answer 2

Answer: power - the work done per unit time in order to maintain electric current in the circuit

Now 1 kilowatt= 1000watt and kilowatt hours is another thing it is related to energy

Explanation:

1 kilowatt hours= 3.6000000 joules
