Answer

Explanation:

Step1: Recall power formula

The power formula is $P = VI$, where $P$ is power in watts (W), $V$ is voltage in volts (V), and $I$ is current in amperes (A).

Step2: Substitute given values

Given $V = 120$ V and $I=\frac{1}{3}$ A. Substitute into the formula: $P=120\times\frac{1}{3}$.

Step3: Calculate power

$P = 40$ W.

Answer:

40 W
