Question
Differentiate between energy and power.

Answer

Energy Power
1. Energy of a body is its capacity to do work. (i) Power of a source is the energy spent by it in 1s.
2. Energy spent does not depend on time. (ii) Power spent depends on the time in which energy is spent.
3. S.I unit of energy is joule (J). (iii)S.I unit of power is watt (W)
