A high-intensity searchlight on an emergency rescue helicopter is connected to a 28.0 V DC electrical supply.

A current of 15.5 A flows through the searchlight.

Calculate the electrical power supplied to the searchlight.

Use the equation:

power=potential difference×current \text{power} = \text{potential difference} \times \text{current} power=potential difference×current
