A full wave rectifier circuit along with the output is shown in the figure. The contribution from diode $D_1$ are:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → A and C only
In the positive half cycle of input ac signal diode $D_1$ if forward bias and $D_2$ is reverse biased so the output voltage A and C are due to $D_1$.
