Amplifier is electronics devices save output energy and give (save energy) to input energy with higher amplitude it's mean transmission energy between output energy and input (power supply).

Op_amp has large input impedance to avoid loading effect. If Op_amp has very low input impedance, it would draw significant amount of current into it. It would act as large load on the circuit.
The fact that op_amp high i/p impedance ensure that it consume very little or no current from circuit.

1. High voltage gain.
2. Perfect balance V1 = V2.
These characteristics are also IDEAL OPAMP.
2. Perfect balance V1 = V2.

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

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