2. In the circuit below, assume R1=R2 = 1k0 and Rg = Rf = 10kQ Vcc= -VEE = 20V Vo a. Find the differential gain, V2-V1 b. Assuming that the op-amp is rail-to-rail (Vout can go all the way to the power supply), what is the largest difference in voltage (V2-V1) that will be properly amplified by this circuit?

Question
**Problem 2: Operational Amplifier Circuit Analysis** In the circuit below, assume the following values: - R1 = R2 = 1kΩ - Rg = 10kΩ - Rf = 10kΩ - \( V_{CC} = -V_{EE} = 20V \) **Tasks:** a. Find the differential gain, \(\frac{V_o}{V_2 - V_1}\). b. Assuming that the op-amp is rail-to-rail (meaning \(V_{out}\) can swing all the way to the power supply rails), determine the largest difference in voltage \((V_2 - V_1)\) that can be properly amplified by this circuit. **Circuit Explanation:** - The circuit is an operational amplifier configured for differential input. - Resistors R1 and R2 offer balancing for the inputs \(V_1\) and \(V_2\). - Resistors Rf and Rg form a feedback network that sets the gain of the amplifier. **Diagram Explanation:** - The op-amp is depicted with two input terminals connected to resistors R1 and R2, leading to respective voltages \(V_1\) and \(V_2\). - The feedback path includes resistor Rf connecting the output \(V_o\) back to the inverting input. - Resistor Rg connects the inverting input to the ground, setting up the differential amplification configuration.
