Diodes and their applications

Explanation of question 9

A full-wave bridge rectifier is correctly connected to a 6V, 50Hz supply. The ripple frequency will be

  1. 200Hz
  2. 100Hz
  3. 50Hz
  4. 25Hz

The answer is :- 2 For half-wave rectification, the ripple frequency is the same as the supply frequency. For full-wave rectification (using either two diodes or a bridge circuit), the ripple frequency is twice the supply frequency.
