Node Equation Method (Node
- Find essential nodes of the circuit
- Number of equations = essential nodes - 1
- Choose a reference node (arbitrary, but usually the one that is
connected to the most elements)
- Write the voltage references (plus and minus sign) with a voltage rise from
the reference node to the other nodes.
- Draw the arrows out of the nonreference node and make the terms positive in
the node voltage equation.
- Then write the node voltage equations
