Q157 / 180 · KCET 2013 · Physics

The width of the depletion region in a $p-n$ junction diode is

  • Correct answer
    A
    increased by reverse bias
  • B
    increased by forward bias
  • C
    decreased by reverse bias
  • D
    independent of the bias voltage

Solution

In a p-n junction diode, thickness of depletion layer increases in reverse biasing.

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