# 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.
