Question

Which one of the entries given in the truth table is true for the following logic circuit?

Entry No.	Input A	Input B	Output Y
1.	0	0	1
2.	0	1	0
3.	1	0	1
4.	1	1	0

• A. 3
• B. 4
• C. 1
• D. 2

Answer 1

Answer: (D)

When the inputs of a AND gate are shorted, then there are two conditions arise:
(i) When the input is 0 , then the output is $0.$
(ii) When the input is $1,$ then the output is $1.$
Hence, by using above two conditions, the output is 0 for the given logic circuit. When $A=0,B=1$
