An electric oven of 2 kW power rating is operated in a domestic electric circuit [220V] that has a current rating of 5 A. What result do you expect ? Explain.

Text Solution

Verified by Experts

Given :
Power of the oven = 2 kW = 2000W, Voltage = 220 V.
Using P = VI , l = `(P)/(V) = (2000)/(220) = 9 . 09 A`
This exceeds the specified current rating of the oven which is 5A . Hence electric fuse melts and breaks the circuit.
