In a full wave rectifier circuit operating from 50 Hz mains frequency, the fundamental frequency in the ripple would be
  1. (A)50 Hz
  2. (B)25 Hz
  3. (C)100 Hz✓ Correct
  4. (D)70.7 Hz

Answer: (C)

Solution

A full-wave rectifier flips the negative half of each input cycle upward, so every single input cycle yields two output humps. The ripple therefore repeats at twice the mains frequency, Hz.
