Q. |
When two semiconductors of p-and n- type are brought in contact, they form p-n junction which acts like a/an – |
A. | Conductor |
B. | Oscillator |
C. | Rectifier |
D. | Amplifier |
Answer» C. Rectifier | |
Explanation: P-n junction is a device which flows current in one direction when it is forward biased and when it is reverse biased it doesn't flow any current through it. So it acts as an rectifier device to convert sinusoidal current to unidirection. 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. |
