AC theoryQuestion 984 of 1506

In a series R-L-C circuit, the inductive reactance is larger than the capacitive reactance. What angle does the inductor impedance have?

  1. +90 degrees
  2. -90 degrees
  3. 0 degrees
  4. It depends on the supply voltage
Show answer

Correct answer: +90 degrees

Phase angles of component impedances are fixed, and for an inductor it is +90 degrees.
