MCQ
Given below are two statements:

Statement $I$ : Photovoltaic devices can convert optical radiation into electricity.

Statement $II$ : Zener diode is designed to operate under reverse bias in breakdown region.

In the light of the above statements, choose the most appropriate answer from the options given below

  • A
    Statement $I$ is incorrect but Statement $II$ is correct.
  • ✓
    Both Statement $I$ and Statement $II$ are correct
  • C
    Both Statement $I$ and Statement $II$ are incorrect.
  • D
    Statement $I$ is correct but Statement $II$ is incorrect.
✓

Answer

Correct option: B.
Both Statement $I$ and Statement $II$ are correct
b
Statement $I$ : Photocell/solar cell convert light energy into electric energy/current.

Statement $II$ : We use zener diode in reverse biased condition, when reverse biased voltage more than break down voltage than it act as stablizer.
