Question

If a microwave is determined to use 840 W of power on a 120 V circuit, how many amperes does it need to run?

Answer 1

7 amperes

Explanation:

Given:

Power (P) = 840 W

Voltage (V) = 120 V

We can calculate the current value as follows:

`\begin{gathered} I=(P)/(E) \\ \\ \text{ We replacing:} \\ \\ I=(840)/(120) \\ \\ I=7\text{ A} \end{gathered}`

Therefore, the number of amperes is 7
