ANSWER:

588.32 watts

STEP-BY-STEP EXPLANATION:

Given:

Resistance (R) = 69 Ω

Current (I) = 2.92 A

We can calculate the power as follows:

[tex]\begin{gathered} P=I^2\cdot R \\ \\ \text{ We replacing:} \\ \\ P=2.92^2\cdot69 \\ \\ P=588.32\text{ W} \end{gathered}[/tex]

The power used is 588.32 watts
