Question 8

The potential difference across an electric motor is 12 V.

The current in the motor is 0.15 A.

Calculate the energy transferred to the motor in two minutes.

Use the equation:

energy transferred=current×potential difference×time in seconds \text{energy transferred} = \text{current} \times \text{potential difference} \times \text{time in seconds} energy transferred=current×potential difference×time in seconds
