Answer:
Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit.
The SI unit of power is the watt, one joule per second...
We know that, power is basically work done in unit time.
That is, Power=work/time
And, work=potential different × charge
And, charge= I×t (current passing through a conductor in unit time)
Therefore, power=(potential difference×charge)/(charge/current)
=potential difference×current
=200V × 0.5A
100watt.
