Out of the following statements, which statements explain the difference between forward biasing and reverse biasing in a p-n junction correctly?
Forward biasing in a p-n junctionReverse biasing in a p-n junction
(A) p-side is connected to the +ve terminal and n-side to the -ve terminal of the battery.p-side is connected to the -ve terminal and n-side to the +ve terminal of the battery.
(B) Depletion layer becomes thicker.Depletion layer becomes thin.
(C) Resistance across the p-n junction increases.Resistance across the p-n junction decreases.
(D) the current is due to majority charge carriers.the current is due to minority charge carriers.
Choose the correct answer from the options given below:

  1. A (A), (B) and (D) only
  2. B (B) and (D) only
  3. C (A) and (D) only

Answer & Solution

Correct Answer

(C) (A) and (D) only

Step-by-step Solution

Detailed explanation

(A) is correct: p-side to +ve, n-side to -ve for forward bias; p-side to -ve, n-side to +ve for reverse bias. (B) is incorrect: Depletion layer becomes thin in forward bias and thick in reverse bias. (C) is incorrect: Resistance decreases in forward bias and increases in reverse…
