1. Generating Circuit Equations
Label all voltages and resistors.
Label all currents; pick direction.
Label loops.
Label nodes.
Make loop equations; start at node. *see next slide for rules
Make node equations.
Set up system of independent equations.

2. For each loop … Start at node; go to first component
Voltage source – V positive if you come to negative terminal first
Resistor – IR positive if you come to the resistor going against the current

3. For each node … Start at node
Currents into node are positive; currents out of node are negative.
Sum of all currents at node are zero.
