With increasing biasing voltage of a photodiode, the photocurrent magnitude :

Question:

With increasing biasing voltage of a photodiode, the photocurrent magnitude :

  1. (1) remains constant

  2. (2) increases initially and after attaining certain value, it decreases

  3. (3) Increases linearly

  4. (4) increases initially and saturates finally


Correct Option: , 4

Solution:

(4) I-V characteristic of a photodiode is as follows :

On increasing the biasing voltage of a photodiode, the magnitude of photocurrent first increases and then attains a saturation.
