For Z=3-j4 ohm, the impedance angle is closest to?

  • A-53.1 degrees
  • B+53.1 degrees
  • C-36.9 degrees
  • D+36.9 degrees
Report an error
Correct Answer: A. -53.1 degrees
Explanation: The angle is tan^-1(-4/3)≈-53.1 degrees, indicating capacitive behavior.
Reference: Standard network theory: impedance phase numerical
