The inverting amplifier in the circuit shown has an input resistance of 400 kΩ, an output resistance of 4 kΩ, and an open-loop gain of 100, 000 . Assume that the amplifier is operating in its linear region. Using the realistic model of the op-amp, calculate the voltage gain (v0/vg) of the amplifier for and R1 = 5 kΩ and R2 = 100 kΩ. In your answer, use point/dot as decimal point. Do NOT use comma. Write your answer with 4 digits to the right of the decimal point. If you find a negative value, don't forget to include a minus sign. (For example, if you calculate the gain as -7.569683, then you should write -7.5697)
