Question

An electric motor is rated at 500 W. How much electrical energy will it require in 1 minute?

Answer 1

ANSWER:

30000 J

STEP-BY-STEP EXPLANATION:

Given:

Power (P) = 500 W

Time (t) = 1 min = 60 sec

We can calculate the electrical energy by the following formula:

$\begin{gathered} E=P\times t \\ \\ \text{ We replacing} \\ \\ E=500\cdot60 \\ \\ E=30000\text{ J} \end{gathered}$

The electrical energy required is 30000 joules.
