Question 106 of 209

The I−V\text{I}-\text{V} characteristics of an LED\text{LED} is:

Show answer and solution

Answer: (C)

For same value of current higher value of voltage is required for higher frequency hence,

VTh∝ΔEg∝1λ{V}_{Th}\propto \Delta {E}_{g}\propto \dfrac{1}{\lambda }

LED works in forward Bias. This graph is correct.
