With forward bias mode, the p - n junction diode

Options

  1. Ais one in which width of depletion layer increases
  2. Bis one in which potential barrier increases
  3. Cacts as closed switch
  4. Dacts as open switch

Correct answer

C. acts as closed switch

Step-by-step solution

​When a p - n junction is in forward bias, it allows current to flow through it with minimal resistance. Hence we can say, it acts like a closed switch
