When a kettle is switched on, the potential difference across its heating element is 230 V and the current in the heating element is 10 A.
Calculate the resistance of the heating element.
Use the equation: potential difference=current×resistance\text{potential difference} = \text{current} \times \text{resistance}potential difference=current×resistance
