Question 8

An electric motor in a model crane transfers 180 J of energy when connected to a 12 V power supply.

Calculate the total charge that flows through the motor.

Use the equation:

energy transferred (E)=charge flow (Q)×potential difference (V) \text{energy transferred } (E) = \text{charge flow } (Q) \times \text{potential difference } (V) energy transferred (E)=charge flow (Q)×potential difference (V)
