The input a.c. voltage of frequency 60 ~Hz is applied to half-wave rectifier and also to full-wave rectifier. The output frequency in case of half-wave rectifier and that in case of full wave rectifier is respectively.

Options

  1. A120 ~Hz , 60 ~Hz
  2. B60 ~Hz , 120 ~Hz
  3. C60 ~Hz , 60 ~Hz
  4. D120 ~Hz , 120 ~Hz

Correct answer

B. 60 ~Hz , 120 ~Hz

Step-by-step solution

In a half-wave rectifier, one pulse is obtained for each wave and hence 60 pulses will be obtained per second. In a full wave rectifier, two pulses are obtained for each wave and 120 pulses are obtained per second.
