Lecture 06 - Node Voltage Analysis

2. Introduction to Node Voltage Method
More direct than branch equations
Fewer equations to solve
Choose one node as reference
Express all variables in terms of node voltages
Solution is set of node voltages w.r.t. chosen reference node
Solution completely defines the circuit
