what is difference between energy and power
Power is like the strength of a weight lifter and Energy is the measure of how long he can sustain the output of power. While energy is ‘joules’, power is ‘joules per second’. Well, in another words Power is ‘watt’ and Energy is ‘watt-hour’.
Another difference is that energy can be stored whereas power cannot be stored. While energy comes with a time component, Power is an instantaneous quantity. Power cannot vary but remains constant. Meanwhile energy accumulates predictably.
