The given circuit consists of a combination of NOT, AND, and OR gates. The truth table is derived as follows:
1. The NOT gates invert the inputs \(A\) and \(B\).
2. These inverted values are then input into the AND gates, and the output of each AND gate is determined.
3. Finally, the outputs of the AND gates are fed into the OR gate to produce the final output \(X\).
Truth Table Analysis:
(A) When \(A = 0\) and \(B = 0\), the output \(X = 1\).
(B) When \(A = 0\) and \(B = 1\), the output \(X = 0\).
(C) When \(A = 1\) and \(B = 0\), the output \(X = 1\).
(D) When \(A = 1\) and \(B = 1\), the output \(X = 0\).
Hence, the correct truth table corresponds to Table 3.
Which logic gate is represented by the following combinations of logic gates?



Which of the following circuits has the same output as that of the given circuit?
A substance 'X' (1.5 g) dissolved in 150 g of a solvent 'Y' (molar mass = 300 g mol$^{-1}$) led to an elevation of the boiling point by 0.5 K. The relative lowering in the vapour pressure of the solvent 'Y' is $____________ \(\times 10^{-2}\). (nearest integer)
[Given : $K_{b}$ of the solvent = 5.0 K kg mol$^{-1}$]
Assume the solution to be dilute and no association or dissociation of X takes place in solution.
Inductance of a coil with \(10^4\) turns is \(10\,\text{mH}\) and it is connected to a DC source of \(10\,\text{V}\) with internal resistance \(10\,\Omega\).
