Question

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

Answer 1

Answer:

• Current = 9.09A

Explanation:

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

➡ P = V × I

➡ I = P/V

Substituting the values, we get

➡ I = 2000 W/220 V = 9.09 A

The current drawn by the electric oven is 9.09 A which exceeds the safe limit of the circuit. This causes the fuse to melt and break the circuit.
