Physics Question on Semiconductor electronics: materials, devices and simple circuits

In the following circuit, the correct relation between output (Y) and inputs A and B will be:

Fig. Circuit

A

Y = AB

B

Y = A + B

C

Y=AB‾Y = \overline{AB}

D

Y=A+B‾Y = \overline{A + B}

Answer

Y=AB‾Y = \overline{AB}

Explanation

Solution

The correct answer is (C) : Y=AB‾Y=\overline{AB}

Fig. Circuit

The shown circuit is a combination of AND gate and a NOT gate.
⇒Y=AB‾⇒ Y = \overline{AB}
