A heating element in a heated glove is connected to a battery. A voltmeter connected across the heating element reads 7.5 V and an ammeter in series with it reads 0.30 A.
The equation linking potential difference, current and resistance is:
potential difference=current×resistance\text{potential difference} = \text{current} \times \text{resistance}potential difference=current×resistance
Use the meter readings to calculate the resistance of the heating element.
