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

*P*) is given by the expression,*P* = *VI*

Where,

Voltage,*V* = 220 V

Current, *I* = 5 A

*P*= 220 x 5 = 1100 W

Energy consumed by the motor = Pt

Where,

Time, *t* = 2 h = 2 x 60 x 60 = 7200 s

∴ *P* = 1100 x 7200 = 7.92 x 10^{6} J

Therefore, power of the motor = 1100 W

Energy consumed by the motor = 7.92 x 10^{6} J
