Question

an electric motor takes 5A from 220V line. Determine the power of the motor and energy consumed in 2hours.

Answer 1

Answer:

7920000 J

Explanation:

Power of the electric motor is given by P = VI Where, V = 220 V and I = 5 A So, Power P = 220 × 5 = 1100 W Now, the energy consumed = Power × time Where, P = 1100 W t = 2 hours = 2 × 60 × 60 seconds = 7200 seconds So, the energy consumed E = 1100 × 7200 J = 7920000 J
