Which of the following terms does not represent electrical power in a circuit?

An electric motor takes 5A from a 220 V line. Determine the power of the motor and the energy consumed in 2 h.

A piece of wire of resistance R is cut into five equal parts. These parts are then connected in parallel. If the equivalent resistance of this combination is R', then the ratio R/R' is:

An electric bulb is rated 220 V and 100 W. When it is operated on 110 V, the power consumed will be:

Two conducting wires of the same material and of equal lengths and equal diameters are first connected in series and then in parallel in a circuit across the same potential difference. The ratio of heat produced in series and parallel combination would be:
