Linear Equation Circuit Solution • We can always solve a linear circuit by 1. Writing Down All KVL Equations Resulting From Voltage Sources 2. Writing Down KCL Equations At Each Simple Non-reference Node Including All Unknown Currents 3. Writing Down All Element Equations Including Dependent Source Control Variable Equations •T he Result Will Be Solvable But Potentially Large The Supernode Concept Reduces The Scale of the Problem 2

Logical Procedure • Identify Nodes • Choose a Ground Node (if necessary) – Negative terminal of constant Voltage Source if Possible • Write Down KVL Equations Associated With Voltage ources Sources – This clears up trivial variables and identifies Supernodes • Write Down Node/Supernode KCL Equations
