Problem 2The input voltage to this circuit vin is 0.2 V and the power rails are +12 V.R,=4 kNR,=1 kNVinout1kN=R,4kN=R,What is the output voltage, vout, in V? Provide your answer with 3 significant digits.Q+ 10

For ideal opamp voltage at non inverting terminal is same as voltage at inverting terminal. And also for ideal opamp current entering the inverting terminal and non inverting terminal is zero. Apply KCL at non inverting terminal to find output voltage. Input resistance is the resistance seen by the voltage source.
