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

I=5A

V=220V

P=VI

P=5×220

p=1100W

p=1100/1000

P=11/10 kW

time=2 hour

E= P×t

E=11/10 × 2

E=11/5

E=2.2 Unit

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
