Question

the current flowing through a lamp is 1.5 a. it is plugged into a 120-v outlet. what is the resistance of the lamp?

Explanation:

Step1: Recall Ohm's Law

Ohm's Law is $R = \frac{V}{I}$, where $R$ is resistance, $V$ is voltage, and $I$ is current.

Step2: Substitute values into formula

Given $V = 120\ \text{V}$ and $I = 1.5\ \text{A}$, calculate $R = \frac{120}{1.5}$.

Step3: Compute the result

$\frac{120}{1.5} = 80$

Answer:

80
