Solution


Q.

Name the logic gate equivalent to the diagram attached              [2023]
1 OR  
2 AND  
3 NAND  
4 NOR  

Ans.

(4)

Circuit is closed when neither A nor B is closed ⇒ current flows for A = 0 B = 0 when either or both of A & B is closed we get current bypass from switch

Hence it is “NOR” gate
