Question

An electric motor takes 5A current from a 220V line. Calculate the power. Also calculate the energy consumed in 5 hours

Answer 1

Current (I)=5A
Potential difference (V)=220 V
Time(t)=5 hr
Power(P)=?
Energy(E)=?

By using the formula,P=VI
               P= 220 V× 5A
                 =1100 W

By using the formula,E=P×t
                                E=1100 W× 5 hr
                                   =(1100/1000)Kw × 5 hr
                                   =5.5 kwh

∴ Power=1100 W, Energy consumed=5.5 Kwh
