A full wave bridge rectifier uses
Correct answer: C. four diodes
- A. one diode
- B. two diodes
- C. four diodes
- D. no diodes
Explanation
Four diodes arranged in a bridge route both halves of the cycle through the load in the same direction, so the output has twice the pulse frequency of a half wave circuit and is far easier to smooth. Its advantage over the two diode centre tap arrangement is that it needs no centre tapped transformer. Two of the four diodes conduct during each half cycle.

About Rectification
Rectification converts alternating current into unidirectional current using semiconductor diodes. The content includes half wave and full wave rectifiers, bridge circuits, output waveforms, ripple and smoothing with capacitors, with the difference between rectification and voltage regulation kept clear.
