Question
The image depicts an electrical circuit featuring operational amplifiers (op-amps), resistors, and a voltage source. Let's break down the components and configuration: 1. **Voltage Source**: - There is a 1V voltage source connected to the circuit. 2. **Resistors**: - There is a 5 kΩ resistor connected in series immediately after the voltage source. - A 10 kΩ resistor is connected to the inverting input of the first op-amp. - The output of the first op-amp (Vx) leads to a 12 kΩ resistor. - The second op-amp has feedback from its output through a 15 kΩ resistor back to its inverting input. - An 8 kΩ resistor connects from the output of the second op-amp to ground. - Another 12 kΩ resistor is connected from the junction of Vx and the 12 kΩ resistor to ground. 3. **Operational Amplifiers**: - The first op-amp is configured with its non-inverting input connected to the voltage divider formed by the 1V input through the 5 kΩ resistor. It outputs to Vx. - The second op-amp receives input from Vx and uses a feedback loop with the 15 kΩ resistor. Its non-inverting input is grounded. **Instruction**: - The task is to determine the value of Vx in this configuration. The op-amps are assumed to be ideal, meaning they have infinite input impedance, zero output impedance, and the voltage difference between the inverting and non-inverting terminals is zero when in a closed loop. The configuration suggests a circuit analysis using principles of superposition, node voltage method, or other circuit theories related to operational amplifiers.
