Engineering Op Amp Circuit - Simple non-inverting circuit question

Click For Summary
The discussion revolves around a non-inverting op-amp circuit and the setup of the relevant equations. The user presents an equation involving resistances and a cosine function but questions its correctness due to the absence of a variable for R1. Another participant points out that the equations should reflect Kirchhoff's Current Law (KCL), emphasizing that they should represent currents leaving a node. The confusion stems from the interpretation of the circuit parameters and their representation in the equations. Clarification on the correct application of KCL in this context is needed for accurate analysis.

Op Amp Circuit -- Simple non-inverting circuit question

Homework Statement



Image2. The attempt at a solution

0V*(236k/R1) + (-0.1cos(500t)*(236k/1k)) = 23.7cos(500t)

Is this the correct setup of the equation because there is no R1 variable to solve for...?

I am not understanding your equations. KCL equations are in the form of currents leaving a node, so voltages divided by resistances...
