I - V characteristics of photodiode for different illumination intensities I₁, I₂, I₃ and I₄ are drawn as follows. Then the maximum intensity among them is (a) I₁ (b) I₂ (c) I₃ (d) I₄

Answer: (d). In reverse bias, photocurrent is proportional to the light intensity. Curve I₄ shows the largest reverse current. So the answer is (d) I₄.

I - V characteristics of photodiode for different illumination intensities $\text{I}_1, \text{I}_2, \text{I}_3$ and $\text{I}_4$ are drawn as follows. Then the maximum intensity among them is

Show answer and solution

Answer: (d)

In reverse bias, photocurrent is proportional to the light intensity.
Curve $I_4$ shows the largest reverse current.
So the answer is (d) $I_4$ .
