How could I find the current and voltage in this circuit (io and vo)?

### Circuit Diagram Analysis The diagram illustrates an operational amplifier circuit with several resistors and a voltage source. The key components and their connections are described below: 1. **Voltage Source**: - A 1 V DC voltage source is present on the left side of the circuit. 2. **Resistors**: - There are five resistors in the circuit: - A 10 kΩ resistor is connected to the top of the voltage source. - A 90 kΩ resistor is in series with the 10 kΩ resistor. - A 100 kΩ resistor is positioned in the feedback loop of the operational amplifier. - A 50 kΩ resistor is connected to the inverting input of the operational amplifier and to the ground. - Another 10 kΩ resistor is connected at the output side of the op-amp leading to the output voltage \( v_o \). 3. **Operational Amplifier (Op-Amp)**: - The op-amp has non-inverting (+) and inverting (-) inputs. - The output of the op-amp is indicated as \( i_o \). - The feedback loop is formed by the 100 kΩ resistor connecting the output back to the inverting input. 4. **Output**: - The output voltage \( v_o \) is measured across the rightmost 10 kΩ resistor. This configuration suggests a classic inverting amplifier setup where the feedback and input resistors determine the gain of the amplifier. The specific values of the resistors affect the gain and stability of the circuit.
