Can you explain the answer of this question below:The inputs of a NAND gate are connected together. The resultant circuit isA:NOT gateB:AND gateC:OR gateD:None of the aboveThe answer is a.

Question

Accepted Answer

The equation of NAND gate is
Y=Aˉ.Bˉ
When both the terminals are connected together.
A=B=A
Y=Aˉ.Aˉ=Aˉ.Aˉ=Aˉ
Which is nothing but the equation of NOT gate.
Y=Aˉ
Option A is the correct answer.

Answer

In nand gate if input is 0 1 then and AND will be 0 but nand means not AND so ans is 1. rest I leave it on u to solve

Answer

Because bar of A+A is equal to that of A.A

Answer

Understanding the NAND Gate
A NAND gate is a digital logic gate that produces an output which is false only when all its inputs are true. The truth table for a NAND gate with two inputs (A and B) is as follows:
- Input A = 0, Input B = 0 → Output = 1
- Input A = 0, Input B = 1 → Output = 1
- Input A = 1, Input B = 0 → Output = 1
- Input A = 1, Input B = 1 → Output = 0
Connecting Inputs Together
When the inputs of a NAND gate are connected together, both inputs become the same. Let’s denote this common input as A. Therefore, the NAND gate now has two inputs: A and A.
Truth Table for the Combined Input
The truth table will now look like this:
- Input A = 0 → Output = 1 (since 0 NAND 0 = 1)
- Input A = 1 → Output = 0 (since 1 NAND 1 = 0)
Identifying the Resultant Function
The resultant output from this configuration behaves like a NOT gate:
- When A = 0, Output = 1 (NOT 0 = 1)
- When A = 1, Output = 0 (NOT 1 = 0)
Conclusion
Thus, connecting both inputs of a NAND gate together effectively transforms it into a NOT gate, making the correct answer option 'A'. This showcases how versatile logic gates can be in circuit design.

Answer

Because NOT gate one of the input gate
