The inverting amplifier in the circuit shown has an input resistance of 400 kn, an output resistance of 4 kn, 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 (vo/vg) of the amplifier for and R1-5 kQ and R2=100 kQ. 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) R2 www R1 ww VE Vo
