A heating element in a stove is designed to receive $$3000 \,W$$ when connected to $$240 \,V$$. Assuming the resistance is constant, calculate the current in the heating element.
Given:
The power rating of the stove $$P=3000\ W=3\ kW$$
Voltage $$V=240\ V$$
$$\underline{\text{Calculating current}}:$$
We know, $$P=VI$$, where $$I$$ is the current.
$$\therefore I=\dfrac{P}{V}=\dfrac{3000}{240}=12.5\ A$$
