Question

When the two inputs of a NAND gate are shorted, the resulting gate is :

• A. NOR
• B. OR
• C. NOT
• D. AND

Answer 1

The correct option is C NOT

The circuit diagram of a NAND gate when its two inputs are shorted, is given as
NAND = AND + NOT
The truth table of this logic gats is given in the figure below.
Hence, if the input is zero then output is 1 and when input is 1 then output is zero.
So, the resulting gate is NOT gate.
