Match List-I with List-II. List-I List-II (A) Solar cell (I) Forward bias (first quadrant) (B) Photodiode (II) Reverse bias (third quadrant) for light detection (C) Light emitting diode (III) Reverse breakdown region (third quadrant) (D) Zener diode (IV) No external bias (fourth quadrant) Choose the correct answer from the options given below:

Options

  1. A(A)-(I), (B)-(II), (C)-(IV), (D)-(III)
  2. B(A)-(IV), (B)-(II), (C)-(I), (D)-(III)
  3. C(A)-(IV), (B)-(III), (C)-(I), (D)-(II)
  4. D(A)-(II), (B)-(IV), (C)-(I), (D)-(III)

Correct answer

B. (A)-(IV), (B)-(II), (C)-(I), (D)-(III)

Step-by-step solution

A solar cell operates without any external bias and delivers power to a load, so its V - I characteristics are plotted in the fourth quadrant. A photodiode is operated in reverse bias (third quadrant) to detect optical signals. A light emitting diode (LED) operates in forward bias (first quadrant) to emit light. A Zener diode is designed to operate in the reverse breakdown region (third quadrant) as a voltage regulator. Therefore, the correct matching is (A)-(IV), (B)-(II), (C)-(I), (D)-(III). Answer: (A)-(IV), (B)
