alleryA full-wave rectifier built with two diodes needs a transformer with a:
ASolid iron core
BSingle winding
CBuilt-in fuse
DCentre tap
Answer & Solution
Correct answer: D. Centre tap
1. The output is taken between the diodes' common point and the middle of the secondary.
2. So the secondary needs a middle connection.
3. That is a centre tap.
