Inverting amplifier

In the (normal) case of a large open-loop gain of the opamp (typically >100 dB) the feedback mechanism will force the inverting input terminal to be virtually grounded. In this limit the closed-loop amplification factor of the circuit will be determined solely by the resistance values.

Turn on the voltage source and check the circuit for different values of the resistances and/or the open-loop gain of the opamp.
