Question
Which type of rectifier circuit uses two diodes and a center-tapped transformer?
Answer Options
- A) Full-wave
- B) Full-wave bridge
- C) Half-wave
- D) Synchronous
Correct Answer: A
Explanation
A rectifier circuit converts Alternating Current (AC) into pulsating Direct Current (DC). The full-wave rectifier circuit is one of the most common types and is characterized by its use of two diodes and a center-tapped transformer.
The center tap acts as the common ground reference, and the two end taps are 180^\circ out of phase. Each diode conducts current during one half of the AC cycle (positive and negative), resulting in a pulsating DC output at twice the input frequency. This method is simpler than a bridge rectifier but requires the use of a center-tapped transformer.
