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

Explanation

Power of the electric motor is given by: P = VI Where, V = 220 V and I = 5 A So, Power P = 220 x 5 = 1100 W Now, the energy consumed = Power x time Where, P = 1100 W t = 2 hours = 2 x 60 x 60 seconds = 7200 seconds So, the energy consumed E = 1100 x 7200 J = 79,20,000 J
