Question

Figure shows a full wave bridge rectifier circuit. The input a.c. is connected across

• A. A and B
• B. A and C
• C. B and D
• D. B and C

Answer 1

The correct option is C B and D

Given, Full wave bridge rectifier circuit,

Here, The input a.c. is connected across $B$ and $D,$

If we connect input a.c. across $A$ and $C$, then we will get same voltage at $B$ and $D$, which implies output is zero.

So we won't connect input a.c across $A$ and $C$.

So we should connect input a.c across $B$ and $D$.

Therefore option $C$ is correct.
