Air Conditioner Power Rating Connected Domestic Electric Circuit Having Current Rating
An air-conditioner of 3.2 kW power rating is connected to a domestic electric circuit having … air-conditioner is switched on?…
Given: P = 3.2kW = 3200W, Fuse current rating = 10 A, V = 220 V
P = VI
3200 = 220 x I
I = 14.54 A
As the required current for the air-conditioner is 14.54A and the rated current of the fuse is 10A, so the fuse will blow cutting off the power supply.
