Current variations are in phase with the applied voltage in an ac circuit with
A) resistors only
B) capacitors only
C) inductors only
D) resistors, capacitors, and inductors

Question

Quizplus · Accepted Answer

In an AC circuit containing only resistors, the current and voltage are in phase, meaning their peaks and zero points occur simultaneously. This is because resistors do not introduce any phase shift between the voltage and current. Capacitors and inductors, on the other hand, cause the current to lead or lag the voltage, respectively, introducing a phase difference.
