About This Question

Subject: physics
Chapter: semiconductor devices
Topic: logic gate and output
Difficulty: Medium
Year: 2025

Solution

Correct Answer:

All inputs high

Boolean Logic: The AND gate performs a logical multiplication ( $Y = A \cdot B$ ).
Truth Table:
- $0 \cdot 0 = 0$
- $0 \cdot 1 = 0$
- $1 \cdot 0 = 0$
- $1 \cdot 1 = 1$
Analysis: The output is '1' (High) only when all inputs are '1' (High).
Circuit Analogy: Similar to two switches in series; the lamp turns on only if both switches are closed.

This medium difficulty physics question is from the chapter semiconductor devices, covering the topic of logic gate and output. It appeared in the 2025 exam.
