The following graph represents

Options

  1. Aforward bias characteristics of a solar cell
  2. Breverse bias characteristics of a Zener diode
  3. Creverse bias characteristics of a photodiode
  4. Dforward bias characteristics of a LED

Correct answer

D. forward bias characteristics of a LED

Step-by-step solution

With increasing voltage, the LED's current rises, leading to light emission due to charge carrier recombination.
