Question

172. The given electrical network is equivalent to
(1) AND gate
(2) OR gate
(3) NOR gate
(4) NOT gate

Answer 1

The given electrical network is equivalent to

(1) AND gate

Answer 2

Answer is option "3"

Explanation:

• If we put input as A=0 B= 0 then we are getting output as F=1
• A logic gate is the elementary building block of a digital circuit, having logic gates that have two inputs and one output
• NOR Gate -  NOT + OR  Gate
• wherein - Y = {A+ B}
• where A and B are inputs and Y is the output  Thus,
• $Y_{1}$= {A+ B}
• $Y_{2}$ = $Y_{1}$ = Ф {A+B}  = A+B
• Y =$Y_{2}$ = {A+B}  & This represents the nor gate
• Hence, the right answer is option 3 "NOR gate"
