Question

an electric motor takes 5A from 220V.
Determine power and energy consumed in 2 hr ​

Answer 1

W = P*t

W = V*i*t

W = 5*220*2

W = 2200 Joule

Answer 2

Answer:

Electric current = 5 A

potential different = 220 V

Time = 2 x 60 x 60 = 7200

P = VI

220 x 5 V

=> 1100 w

Energy consumed by motor,

=> 1100 x 7200

=> 7.92 x 10^6 J
