Question

an electric motor takes 5 ampere from a 220 volt line determine the power of the motor and the energy consumed in 2 hour ​

Answer 1

Answer:

2.2KwH

Explanation:

P=VI

i=5A

v=220v

energy =p*time

p=220*5=1100W

e=1100w*2hrs

e=2200wh

e=2.2KWH

Answer 2

Answer:

0.0022Kwh

Explanation:

5mA = 5*10^-3

P=VI

P=1.1w

energy=1.1* 2  Kwh

energy =0.0022kwh
