Question

An electric stove consumes 5 MJ of energy from a 230 V power supply when turned on for 60 minutes. Find the approximate power.

A.

1389 W

B.

1772 W

C.

1500w

D.

1823W

Solution

Correct option is A

$P = \frac{E}{T} = \frac{5 \times 10^6 \text{ J}}{60 \times 60 \text{ sec}} = 1389 \text{ Watts}$
