Question

A photodiode in reverse biased is irradiated with light of suitable frequency and current in circuit is measured. Characteristics of diode for different illumination intensities I1, I2, I3 and I4 are drawn as follows.

Greatest intensity is (A) I1 (B) I2 (C) I3 (D) I4

When intensity is increased, reverse saturation current also increases. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/b943591e3cf4da4de2729149cea7876f-.png" /> I-V characteristics of a photodiode for different illumination intensity I4>I3>I2>I1.

Q.
A photodiode in reverse biased is irradiated with light of suitable frequency and current in circuit is measured.
Characteristics of diode for different illumination intensities $I_{1}, I_{2}, I_{3}$ and $I_{4}$ are drawn as follows.

Greatest intensity is

$I_{1}$

$I_{2}$

$I_{3}$

$I_{4}$

When intensity is increased, reverse saturation current also increases.

$I - V$ characteristics of a photodiode for different illumination intensity $I_{4} > I_{3} > I_{2} > I_{1}$ .
