Q2. If we invert the circuit of inverter then what will happen
Ans. 
If the circuit of an inverter is inverted, it will act as a buffer.
• Inverting an inverter circuit essentially cancels out the inversion, making it act as a buffer.

• The output will be the same as the input signal, with no inversion.

• This can be useful in certain signal processing applications where a non-inverted signal is needed.
