The number of diodes used in a bridge rectifier is
Correct answer: D. four
- A. one
- B. two
- C. three
- D. four
Explanation
A bridge rectifier circuit typically employs four diodes arranged in a bridge configuration to convert alternating current (AC) to direct current (DC).Incorrect Options and Explanations: (a) one - A single diode cannot create a bridge rectifier circuit. (b) two - Two diodes cannot create a bridge rectifier circuit. (c) three - Three diodes cannot create a bridge rectifier circuit.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
