Unit of electric power may also be expressed as:

(a) Volt-ampere

(b) Kilowatt-hour

(c) Watt-second

(d) Joule-second



Electric power, P is expressed as:

P = V*I


  • V is voltage measured in volts.
  • I is current measured in ampere.

Therefore, electric power can be expressed as volt-ampere.

So, the correct answer is (a).
