Question
**Problem Statement:** 6. Find the output voltage, \( V_o \), assuming the op-amp in the circuit below is ideal. **Circuit Description:** The circuit consists of the following components: - A 5 V voltage source. - Three resistors, each with a resistance of 10 kΩ, connected in various configurations. - An additional resistor of 15 kΩ connected in the feedback loop of the op-amp. - An ideal operational amplifier (op-amp) is used in the circuit configuration. **Circuit Analysis:** 1. **Input Side:** - The 5 V source is connected in series with a 10 kΩ resistor, followed by another 10 kΩ resistor connected to the inverting input of the op-amp (marked with a “–“ sign). 2. **Feedback Loop:** - The 15 kΩ resistor is connected from the output of the op-amp to the inverting input. 3. **Non-Inverting Input:** - The non-inverting input (marked with a “+”) is connected to ground. 4. **Output Side:** - The output voltage \( V_o \) is taken across another 10 kΩ resistor connected to the output of the op-amp. **Goal:** Determine the output voltage \( V_o \) using methods from circuit analysis, assuming the op-amp behaves ideally (infinite gain, infinite input impedance, and zero output impedance). **Analysis Steps:** - Apply Kirchhoff’s laws, superposition theorem, or analyze using virtual short principles of ideal op-amps. - Determine the relationship between input and output voltages considering the feedback network.
