Finding closed loop gain and Ip and In current in op amp

Click For Summary
To find the closed loop gain and input/output currents in an op-amp circuit, the voltage divider rule is applied between resistors R1, R2, R4, and R5. The user is unsure how to proceed after calculating the voltage at these points. The discussion emphasizes the assumptions of ideal op-amp behavior, particularly regarding current through R1 and the potential at the junction of R1 and R2. Understanding these principles is crucial for solving the problem effectively. The thread seeks further clarification and assistance on these calculations.

Finding closed loop gain and Ip and In current in op amp

Homework Equations

The Attempt at a Solution


I started by trying getting voltage divider for points between R1 and R2 as (R2/(R2+R1))Vs and between R4 and R5 similarly. And I'm not sure how to continue on. Any help would be greatly appreciated.

Thanks! Full questions uploaded

Assuming the simplifying properties of an ideal op-amp, what can you say about the current through R1? What then must be the potential at the junction of R1 and R2?
