In a circuit, a logical value of 1 corresponds to a potential of 3 V at a point, and a logical value of 0 corresponds to 0 V. Point Y gives the output. The truth table of the given circuit is:

A B Y 0 0 0 1 0 0 0 1 0 1 1 1
A B Y 0 0 0 1 0 1 0 1 1 1 1 1
A B Y 0 0 0 1 0 0 0 1 0 1 1 0
A B Y 0 0 1 1 0 1 0 1 1 1 1 0

Correct answer: A B Y 0 0 0 1 0 0 0 1 0 1 1 1

Solution

The described circuit is a two-input AND gate. The output Y = 1 only when A = 1 AND B = 1, giving the standard AND truth table.
