Question
The rms current passing through a $50.0-\Omega$ resistor in a sinusoidal ac circuit is $12.0 \mathrm{~A}$. What is the maximum voltage drop across the resistor? Example $21-1$
Step 1
We can use Ohm's law to find the rms voltage $V_{rms}$ across the resistor. Ohm's law states that $V = IR$, where $V$ is the voltage, $I$ is the current, and $R$ is the resistance. In this case, we have $V_{rms} = I_{rms}R$. Show more…
