Question

An electric appliance take 5A from 220v line determine its power and the energy consumed in 2 hours​

Answer 1

Answer:

Hence, the total energy consumed by the motor in 2 hours is 2200 watt-hour.

Answer 2

Answer:

Power=1100 watts

energy in 2 hrs =2200 Joules

Explanation:

Ohms law V= IR

I = V/R = 220/5 = 44 Ohms

Power P = I^2 R = 5^2 × 44 = 25×44 = 1100

P=1100 watts

Energy =Power × time = 1100 × 2

Energy =2200 Joules
