Question

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. [3 MARKS]

Answer 1

Each point: 1 Mark

1. The current drawn by the electric oven can be calculated using following formula: P = VI. Or, I = P/V = 2000 W/220 V = 9.09 A.
2. Here, the oven is drawing 9.09 ampere of current from a 5 ampere source.
3. This means there would be an overload on the circuit. This can result in accidental fire in the circuit.
