Homework Help Overview

The discussion revolves around a basic Kirchhoff's Voltage Law (KVL) circuit problem, where the original poster expresses difficulty in setting up the equations for two loops in the circuit. The context involves analyzing current relationships and applying KVL to derive equations.

Discussion Character

  • Exploratory, Problem interpretation, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to establish the KVL equations for both loops but is struggling with the setup. They mention a known relationship between currents (Ic = Ia + Ib) and seek assistance in formulating the equations.

Discussion Status

Some participants have acknowledged the algebraic nature of the problem, indicating a potential shift towards understanding the mathematical aspects involved. There is no explicit consensus on the setup of the equations, but the discussion reflects a collaborative effort to clarify the problem.

Contextual Notes

The original poster indicates frustration with the problem, suggesting that there may be assumptions or definitions that need further exploration. The repeated mention of the equations implies a focus on the specific relationships within the circuit.

the work i did on that sheet is completely wrong.

I know that Ic = Ia + Ib

but can someone help me set up the equations for the two loops please! I can't seem to figure it out and its frustrating me!

the answer is supposed to be Ic = (RbE1 + RaE2) / RaRb + RaRc + RbRc

Write the KVL equation for the "left loop".

Write the KVL equation for the "right loop".

Write the KCL equation for either junction.
