A full-wave rectifier with diodes D₁ and D₂ is used to rectify 50 ~Hz alternating voltage. The diode D₁ conducts .......... times in one second.

Options

  1. A100
  2. B25
  3. C75
  4. D50

Correct answer

D. 50

Step-by-step solution

In full wave rectifier, one diode works for positive half cycle and another diode works for negative half cycle of alternating voltage. Thus, each diode works one time in one complete cycle of input AC signal. Hence, for 50 ~Hz AC supply, diode D₁ conducts 50 times in 1 ~s .
