Node Equation Method (Node Voltage Method):

- 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
