Q126 / 180 · NEET 2019 (Odisha) · Physics
The circuit diagram shown here corresponds to the logic gate,
- Correct answerANOR
- BAND
- COR
- DNAND
Solution
From the circuit diagram given below, it can be seen that the current will flow to ground if any of the switch is closed. Also, the LED will only glow when current flows through it.
Thus, the truth table for the circuit diagram can be formed as circuit diagram in given solution.
The output $(\mathrm{Y})$ is equivalent to that of NOR gate.
Thus, the truth table for the circuit diagram can be formed as circuit diagram in given solution.
The output $(\mathrm{Y})$ is equivalent to that of NOR gate.
Hence, the correct answer is option: 'A'.
