Q. |
The width of depletion layer of a P-N junction – |
A. | decreases with light doping |
B. | increases with heavy doping |
C. | is independent of applied voltage |
D. | is increased under reverse bias |
Answer» D. is increased under reverse bias | |
Explanation: The total width of the depletion region is a function of applied reverse-bias and impurity concentration. Forward bias decreases the depletion region width whilst reverse bias increases it. |
