Logic Gates question from JEE Main 2023 (6 Apr, Shift 1)

Q103JEE Main 2023 · 6 APR · SHIFT 1Medium

Logic Gates

Name the logic gate equivalent to the diagram attached

Show answer and solution

Answer: (a)

Switches $A$ and $B$ are in parallel, and the LED is connected across them.
Closing either switch shorts the LED, so it does not glow ( $Y = 0$ ).
LED glows only when both switches are open: $Y = \overline{A+B}$ .
So the answer is (a) NOR.
