In an inverting amplifier non-inverting input \[\left( + \right)\] is connected to
A. \[1\,{\text{V}}\] line
B. \[{\text{2}}\,{\text{V}}\] line
C. \[{\text{0}}\,{\text{V}}\] line
D. \[{\text{3}}\,{\text{V}}\] line

Hint: First of all, we will analyze the inverting amplifier for positive and negative connection. We can draw a conclusion from it then. Literally, ground potential is zero joule of work completed on whatever the charge coulomb it holds.

Complete answer:
In the given question, we are talking about a non-inverting input of an amplifier. A voltage-divider-bias negative feedback relation is used by a non-inverting amplifier. There is often a voltage gain greater than one. The voltage gain is positive, meaning that the output is in phase with the input signal for the AC input and the output polarity is the same as the input polarity for the dc input. The input is always given to the inverting terminal in the inverting amplifier, while the non-inverting terminal is grounded.

Hence, the required answer is \[{\text{0}}\,{\text{V}}\] line.The correct option is C.

Additional information:
Non inverting amplifier: An op-amp circuit configuration that generates an amplified output signal is a non-inverting amplifier. This non-inverting op-amp output signal is in-phase with the input signal being applied. In other words, a non-inverting amplifier operates like a circuit of a voltage follower. One of the most common and commonly used types of operational amplifier circuit is the non-inverting amplifier configuration, and it is used in many electronic devices. High input impedance and all the benefits obtained by using an active amplifier are given by the op amp non-inverting amplifier circuit.

Note: It must be remembered that an op-amp circuit configuration which produces an amplified output signal is a non-inverting amplifier. The non-inverting amplifier's high input impedance and low output impedance make the circuit suitable for impedance buffering applications.
