In the circuit, the logical value of \(A =1\) or \(B =1\) when potential at \(A\) or \(B\) is \(5\,V\) and the logical value of \(A=0\) or \(B=0\) when potential at \(A\) or \(B\) is \(0\,V\). The truth table of the given circuit will be :
Pick an option to check your answer.
Answer & Solution
Correct Answer
(A)
\(A\) \(B\) \(y\) \(0\) \(0\) \(0\) \(1\) \(0\) \(0\) \(0\) \(1\) \(0\) \(1\) \(1\) \(1\)
Step-by-step Solution
Detailed explanation
When both \(A\) and \(B\) have logical value \(' 1 '\) both diode are reverse bias and current will flow in resistor hence output will be \(5\) volt i.e. logical value '\(1\)'.
In all other case conduction will take place, hence output will be \(zero\) volt i.e. logical value ' \(0\) '.
So truth table is \((AND\,gate)\)
| \(A\) | \(B\) | \(y\) |
| \(0\) | \(0\) | \(0\) |
| \(0\) | \(1\) | \(0\) |
| \(1\) | \(0\) | \(0\) |
| \(1\) | \(1\) | \(1\) |
