If the AC supply frequency is 50 Hz, the ripple frequency at the output of an ideal full-wave rectifier is?

  • A25 Hz
  • B50 Hz
  • C100 Hz
  • D200 Hz
Report an error
Correct Answer: C. 100 Hz
Explanation: A full-wave rectifier produces two output pulses per input cycle, so its ripple frequency is twice the supply frequency: 100 Hz.
Reference: Standard electronics: rectifier ripple frequency
