When a p-n junction is reverse biased, then the current through the junction is mainly due to
Options
(a) Only diffusion of charges
(b) Only drift of charges
(c) Both drift and diffusion of charges
(d) Neither drift nor diffusion of charges
Correct Answer:
Only drift of charges
Explanation:
When the p-n junction is reverse biased, then the current across the junction is mainly due to drifting of minority carriers.
