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?
Answer
Answer:
$80$
Explanation:
Step1: Recall Ohm's Law
$V = IR$ (where $V$ is voltage, $I$ is current, $R$ is resistance)
Step2: Rearrange for resistance
$R=\frac{V}{I}$
Step3: Substitute values
$R=\frac{120}{1.5}=80$
