Ques. 1JEE Main 2025, 22 January (Morning Shift)

Which of the following circuits represents a forward biased diode? [figure] Choose the correct answer from the options given below:

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

Answer

(4) (B), (C) and (E) only

Solution

Forward bias: the p-side (arrow end) is at a higher potential than the n-side (bar end).

(A): -10<0 (A) reverse

(B): -10>-15 (B) forward

(C): 4>2 (C) forward

(D): p-side -10< n-side -5 (D) reverse

(E): p-side 2>0 (E) forward

(B), (C) and (E)

Answer: (4)
