Question

For the given circuit shown in fig to act as full wave rectifier - ac input should be connected across .......... and ........ the d.c. output would appear across ........ and ..............

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

Answer 1

Answer: (B)

B, D, A, C

To act as full wave rectifier input must be connected across B & D and output must be taken across A & C.

Because we need to get a full wave rectifier, it means that the cycle generated must be continuous. Now when the first cycle of alternating current will come then AB & CD will generate output as they will only have forward biased.

Now when second cycle of alternating current will come then AD & BC will generate output as they have forward biased.
