Consider an ideal differential operational amplifier whose circuit looks like this,
Now in this circuit diagram it is given that, the negative terminal is at 0v.
But if I give a sine wave as input to this op amp whose frequency is high and capacitance of the capacitor is 1.I think almost can't be such a high voltage drop across the capacitor to make the negative terminal at 0v.
If so, is there a virtual ground in this circuit. If yes, please explain me how??
