A p-n junction diode as a rectifier converts
- A a.c. to d.c.
- B d.c. to a.c.
- C high voltage to low voltage.
- D low voltage to high voltage.
Answer & Solution
Correct Answer
(A) a.c. to d.c.
Step-by-step Solution
Detailed explanation
The correct answer is Alternate current to Direct current. A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction.
