Question

Which gate corresponds to the action of parallel switches?
a) NAND gate b) NOR gate c) OR gate
d) AND gate​

Answer 1

The correct option is option C i.e. OR gate.

This is because for parallel switching we should have switches connected in such a way that glowing of bulb or passage of current should not depend on both at same time.

If OR gates are connected in parallel and switching off one OR gate and other keeping on, the bulb will glow.

As in OR gate both inputs doesn't need to be high for high output. If either of the inputs is high then output would be high.
