Question

A full wave rectifier circuit along with the input and output voltage is shown in the figure then output due to diode $D_2$ is :

• A. $A,C$
• B. $B,D$
• C. $B,C$
• D. $A,D$

Answer 1

The correct option is B $B,D$

In the positive half cycle of input $ac$ signal diode $D_1$ is forward biased and $D_2$ is reverse biased so in the output voltage signal, $A$ and $C$ are due to $D_1$. In the negative half cycle of input $ac$ signal $D_2$ conducts, hence output signals $B$ and $D$ are due to $D_2$.
