A p-n junction diode cannot be used

Options

  1. Aas a rectifier.
  2. Bfor converting light energy to electrical energy.
  3. Cfor getting light radiation.
  4. Dfor increasing the amplitude of an a.c. signal.

Correct answer

D. for increasing the amplitude of an a.c. signal.

Step-by-step solution

A p-n junction diode cannot be used for increasing the amplitude of an AC signal. A p-n junction can be used as a rectifier because of its asymmetric current/voltage oroperties that enable current to flow in only one way and it converts light energy to electric energy as well as getting light radiation.
