MCQ
A full wave rectifier circuit along with the input and output voltages is shown in the figure The contribution to output voltage from diode $-2 $ is
- A$A, C$
- ✓$B, D$
- C$B, C$
- D$A, D$
✓
Answer
Correct option: B.
$B, D$
b
(b)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 negative half cycle of Input ac signal $D_2$ conducts, hence output signals $B $ and $D$ are due to $D_2$.
