Question

what is electric energy and electric power ?derive their expression and define their unit?​

Answer 1

The rate at which electric energy is dissipated or consumed in an electric circuit is called electric power. It's SI unit is Watt (W).

power = work done / time taken

we know that work done by current I when it flows for time T under potential difference V is given by :

W = V*I*T joules

so, power = V*I*T / T joules per second

Power, P = V*I joules per second or watt

Explanation:

Hope this will help you
