Question

Among the following which one gives output $1$ in the AND gate.

• A. $A=0,B=0$
• B. $A=1,B=1$
• C. $A=1,B=0$
• D. $A=0,B=1$

Answer 1

The correct option is B $A=1,B=1$

The truth table for AND gate is as shown in the figure. Thus, the output of an AND gate is $1$, if and only if both inputs '$A$' and '$B$' are $1$.
