ANSWER:

7 amperes

STEP-BY-STEP EXPLANATION:

Given:

Power (P) = 840 W

Voltage (V) = 120 V

We can calculate the current value as follows:

[tex]\begin{gathered} I=\frac{P}{E} \\ \\ \text{ We replacing:} \\ \\ I=\frac{840}{120} \\ \\ I=7\text{ A} \end{gathered}[/tex]

Therefore, the number of amperes is 7
