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

Dear Student

Current in the motor, I = 5 amp
Potential difference, V = 220 V
Time = 2 hours
Power of the motor = V × I
= 220 × 5
1100 watt or 1.1. kWh
Energy = power × time
= 1.1 kWh × 2 h.
= 2.2 kWh

Thanks
