Question

2. 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 1

Answer:

power = 1100 watt and energy = 2200 Joule

Explanation:

power = VI

energy = VIt

Answer 2

Answer:

H, energy consumed = 2200 joules

Power ,p= 1100 watt

Explanation:

Given = current = 5A

potential difference = 220V

time = 2h

We know that,

Power = VI

= 5*220

= 1100 Watt

We know that, energy consumed,H = VIT

H = VIT

= 5*220*2

= 2200 joules

Hence the power consumed by the motor is 1100 watt and the energy consumed is 2200 joules
