The device that converts alternating current (AC) to direct current (DC) is called a ________.
- Central
- Identity
- Rectifier
- Adapter / Anti-Corruption Layer
Answer: Rectifier
Rectifier converts AC to DC using diodes. Types: half-wave (single diode, inefficient), full-wave (center-tapped or bridge, better efficiency). Used in power supplies for electronics, battery chargers, and DC motor drives. Filter capacitors smooth the pulsating DC output. Critical component in virtually all electronic devices powered from mains.
