The width of depletion layer of a p-n junction diode, when it is (i) forward biased and (ii) reverse biased respectively

  • A
    increases and increases.
  • B
    decreases and decreases.
  • C
    increases and decreases
  • Correct answer
    D
    decreases and increases.

Solution

(i) The width of depletion layer of a p-n junction decreases when the junction is forward biased. (ii) The width of depletion layer of a p-n junction increases when the junction is reverse biased.

Hence, the correct answer is option: 'D'.
