Nodal Analysis
Nodal analysis is a particular method of solving circuits.
You
write equations in terms of node voltages, and then solve those
equations.
1)
Label every node in the circuit, and label currents through
each voltage source and current source.
2)
Write down any “known” voltage:
Æ
Ground is 0 volts
Æ
Use node voltage constraints across voltage sources
3)
Write KCL equations in terms of the node voltages.
For n nodes, you have n1 equations.
4)
Solve the equations to get the unknown node voltages.
5)
Solve for currents through each element (if you are asked
to do so) using the node voltages.
6)
Solve for power (if you are asked to do so).
