AC theoryQuestion 943 of 1506

What is true of the current in a series AC circuit?

  1. It divides among the components in proportion to impedance.
  2. It is zero in the inductor.
  3. It is the same through every component.
  4. It is larger in the resistor.
Show answer

Correct answer: It is the same through every component.

A series circuit has one path, so the same current flows in all parts.
