Operational amplifier is an amplifier which can be used to perform mathematical operations like integration, differentiation etc.

An ideal opamp is used to make an inverting amplifier. The input terminals of the opamp are at the same potential difference.

I have a small doubt in ideal opamp in case opamp has high input impedance so how the current Will flow in opamp?

Infinite bandwidth means op-amp work within all range of frequencies, but practically it is not possible.

Is it possible to an op-amp have finite Input resistance and zero input offset voltage simultaneously?

1. High voltage gain.
2. Perfect balance V1 = V2.

These characteristics are also IDEAL OPAMP.

What is the actual meaning of the Word Offset Output? Please in details, I want it's answer.

Open loop gain is the gain of op amp without feedback. So what is comparator?

Why the input impedance is infinity?

Why should we take this condition?

Offset output : Showing some error voltage on output without input.
