DC circuitsQuestion 885 of 1506

The current in an inductor reaches a steady maximum value. What is the inductor voltage drop then, if its wire resistance is ignored?

  1. About zero
  2. The full source voltage
  3. Twice the source voltage
  4. Equal to the capacitor voltage
Show answer

Correct answer: About zero

A steady current produces no change in flux, so there is no self-induced voltage.
