### Re: Node Voltage Problem

tknot,

The v2 and v4 node is a natural reference. Why is that same node marked with two different names? Why is the node at the connection of the 3 volt and 5 volts supply set to 0 volts? How do you know that? The 10 ohm resistor in parallel with the 3 volts supply doesn't change any voltages or currents in the circuit. It just puts a load on the 3 volt supply. Remove it and do the calculations.

So, take a cut at solving and post your equations. Solve for nodes v1 and v3.

Nodal Voltage Analysis complements the previous mesh analysis in that it is equally powerful and based on the same concepts of matrix analysis.
