In the figure, there is an ideal opamp connected to a resistor set from the non-inverting input in the circuit. The resistor set on the left feeds the circuit with different voltages while the switches below touch the resistors RA, RB, RC of different values. a.) If we call the input voltage Vi from the left resistor set, derive the expression that gives the Opamp's Gain. b.) Assume a fixed 10V output is read at the output of the circuit. In this case, if the current (I) is 100mA, 10mA and 1mA while the resistors A, B and C are installed, calculate the values of these resistors RA, RB and RC.
