One of the characteristics of an ideal op amp is that it have infinite input impedance/resistance.
Now, I want you to tell me if I am correct :
The voltage source is likely to have some internal resistance.
By having an infinite input resistance, no current is drawn from the voltage source. Hence, if there is no current there is potential drop across the internal resistance of this voltage source.
Could you also explain the importance and requirement of an infinite open loop gain ?
