Quizplus · Accepted Answer

The rms current through an inductor can be calculated using Ohm's law for AC circuits: $ I = \frac{V}{X_L} $, where $ V $ is the rms voltage and $ X_L $ is the inductive reactance. Substituting the given values, $ I = \frac{5.2 \, \text{V}}{0.77 \, \Omega} = 6.8 \, \text{A} $.
