An electric bicycle has a 36 V battery. Its headlamp and its rear lamp are connected in parallel with each other across the battery. When it is lit, the headlamp has a resistance of 120 Ω.
Calculate the current through the headlamp when it is lit.
Use the equation: potential difference=current×resistance\text{potential difference} = \text{current} \times \text{resistance}potential difference=current×resistance
