A full-wave rectifier with diodes \(D_1\) and \(D_2\) is used to rectify \(50 \mathrm{~Hz}\) alternating voltage. The diode \(D_1\) conducts .......... times in one second.
- A \(100\)
- B \(25\)
- C \(75\)
- D \(50\)
Answer & Solution
Correct Answer
(D) \(50\)
Step-by-step Solution
Detailed explanation
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 \(50 \mathrm{~Hz}\) AC supply, diode \(D_1\) conducts 50 times in \(1 \mathrm{~s}\).
