Question

AND gate output is high only when?

RankGuru · Accepted Answer

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