Question

The circuit utilizes an ideal op amp

1)Find I1, I2, I3, IL and Vx.

2) If VO is not to be lower than -6V, find the maximum allowed value for RL.

3) If RL is varied in the range 200Ω to 600Ω, what is the corresponding change in IL and VO?

The image depicts an electrical circuit involving an operational amplifier with feedback. Here is a detailed description of its components: 1. **Voltage Source**: The circuit includes a 1 V voltage source connected to the inverting input of the operational amplifier through a 10 kΩ resistor (R1). 2. **Resistances**: - There is a 10 kΩ resistor (R2) connected in series with the non-inverting input of the operational amplifier and the ground. - A 100 Ω resistor (R3) is connected between the non-inverting input and a node labeled \( V_x \). - A load resistor \( R_L \) is connected to the node \( V_x \). 3. **Currents**: - \( I_1 \): Current flowing through the 10 kΩ resistor connected to the 1 V source. - \( I_2 \): Current flowing through the 10 kΩ resistor connected to the non-inverting input. - \( I_3 \): Current flowing through the 100 Ω resistor. - \( I_L \): Current flowing through the load resistor \( R_L \). 4. **Operational Amplifier**: - The operational amplifier has its inverting and non-inverting inputs connected, creating a feedback loop. - The output of the operational amplifier is labeled \( V_O \), and it is connected to the junction of the load resistor and the 100 Ω resistor. This configuration can be utilized to analyze voltage changes across different nodes and investigate how the operational amplifier influences current flow due to its feedback control.
