Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A) - (III), (B) - (IV), (C) - (II), (D) - (I)
- A Zener diode acts as a voltage regulator (A - III).
- A photo-diode is fabricated with a transparent window to allow light to fall on it (B - IV).
- A solar cell does not require any biasing (C - II).
- An LED is heavily doped and operates in forward bias (D - I).
