Question

Match List-I with List-II (Devices vs Applications).

• A. A-I, B-II, C-III, D-IV
• B. A-IV, B-III, C-II, D-I
• C. A-III, B-I, C-II, D-IV
• D. A-II, B-I, C-III, D-IV

Hint:

Diode → Rectifier, Transistor → Amplifier, Zener → Regulator.

Answer 1

The Correct Option is C

Concept: Different semiconductor devices have specific applications:

Step 1: Diode Used for rectification. \[ A \rightarrow III \]

Step 2: Transistor Used as amplifier. \[ B \rightarrow I \]

Step 3: Tunnel diode Used in oscillators. \[ C \rightarrow II \]

Step 4: Zener diode Used in voltage regulation. \[ D \rightarrow IV \] \[ \therefore \text{Correct answer is (C)} \]
