An electric oven of 2 kW is operated in a domestic electric circuit (220 V) that has a current rating of 5 A. What results do you expect? Explain.

Open in App

Solution

The current drawn by the electric oven can be calculated using following formula:

P = VI or, I = $\frac{P}{V}$ = $\frac{2000 W}{220 V}$ = 9.09 A

Here, the oven is drawing 9.09 ampere of current from a 5 A source. This means there would be an overload on the circuit. This can result in an accidental fire in the circuit.
