With increasing biasing voltage of a photodiode,

Question:

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

  1. increases initially and saturates finally

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

  3. increases linearly

  4. remains constant


Correct Option: 1

Solution:

I-V characteristic of a photodiode is as follows:

On increasing the potential difference the current first increases and then attains a saturation.
