Question
Calculate ix and v0 in the circuit attached. Assume that the output of the Op-Amp is constrained to lie between -15V and 15V.
### Operational Amplifier Circuit Analysis #### Circuit Description: The image presents a basic operational amplifier (op-amp) circuit with several resistors and a voltage source. This circuit can be analyzed to determine various electrical parameters, such as voltage, current, and resistance. #### Components: 1. **Voltage Source:** - A 10 mV voltage source is connected to the input of the circuit. 2. **Resistors:** - There are five resistors in the circuit with the following resistances: - 10 kΩ - 50 kΩ - 20 kΩ - 60 kΩ - 30 kΩ 3. **Operational Amplifier (Op-Amp):** - An operational amplifier is connected with its non-inverting input (+) connected to the voltage source and the inverting input (-) connected to the junction of the 10 kΩ and 50 kΩ resistors. - The op-amp is configured in a closed-loop setup. 4. **Output:** - The output voltage \( v_o \) is taken across the 30 kΩ resistor connected in parallel with the 60 kΩ resistor. #### Circuit Operation: - The circuit operates by amplifying the voltage provided by the voltage source through the operational amplifier. - The current \( i_x \) flows through the 20 kΩ resistor, which lies between the output of the operational amplifier and the junction where the 60 kΩ and 30 kΩ resistors are connected. #### Analysis: - The analysis of this circuit would involve applying Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL) to find the various voltages and currents at different points in the circuit. - Employing the concept of virtual short (the principle that the voltage difference between the inverting and non-inverting terminals of an ideal op-amp is zero), we can find expressions for \( v_o \) (output voltage) and \( i_x \) (current through 20 kΩ resistor). This basic operational amplifier circuit is essential for understanding how op-amps function in amplifying signals in various electronic applications.
