Answer 1

Explanation:

Power (P) is given by the expression,

P = VI

Where,

Voltage,V = 220 V

Current, I = 5 A

P= 220 x 5 = 1100 W

Energy consumed by the motor = Pt

Where,

Time, t = 2 h = 2 x 60 x 60 = 7200 s

ˆ´ P = 1100 x 7200 = 7.92 x 106 J

Therefore, power of the motor = 1100 W

Energy consumed by the motor = 7.92 x 106 J
