An electric motor takes 5 A from a 220 V line. Determine the power of the motor and the energy consumed in 2 h.

Answer:

Given parameters

Voltage (V) = 220 V

Current (I) = 5 A

Time (t) = 2 h = 2 x 60 x 60 = 7200 s

Power (P) is given by the expression,

P = V × I

P= 220 x 5

P = 1100 W

Energy consumed by the motor = P x t

P = 1100 x 7200

P = 7.92 x 106 J

Therefore, power of the motor = 1100 W
Energy consumed by the motor = 7.92 x 106 J
