Question

An electric oven of 1.5kw is operated in a domestic circuit 220v that has a current rateing of 5 ampear what reasult you expect in this case explain

Answer 1

Current drawn by the electric oven can be obtained by the expression,

P = VI

I= P/V

Where,

Current = I

Power of the oven, P = 1.5 kW = 1500 W

Voltage supplied, V = 220 V

I = 1500 / 220

I = 6.818 A

Hence, the current drawn by the electric oven is 6.818 A, which exceeds the safe limit of the circuit. Fuse element of the electric fuse will melt and break the circuit.
