In a parallel circuit of a resistor and an inductor, the total impedance has what phase angle?

  1. Exactly 0 degrees
  2. Exactly +90 degrees
  3. Between 0 and +90 degrees
  4. Between 0 and -90 degrees
Show answer

Correct answer: Between 0 and +90 degrees

The mixed circuit lies between a pure resistor (0 degrees) and a pure inductor (+90 degrees).
