@ShaneYost: A short answer would be whenever the formal methods fail. To get a better insight, you can try to analyse this circuit: (voltage_source) parallel to (resistor) parallel to (current_source + resistor in series). The straightforward mesh and nodal analyses fail here, but you can survive with the rather simple ohm's law, KCL and KVL :)

But then, it gets the job done and the concept is rather simpler; and I guess that was what the OP was looking for. Anyway, thanks for pointing it out :) | |
| Feb 27, 2013 at 22:56 | comment | added | Alfred Centauri | An observation: introducing an unknown current variable for the current through the voltage source takes one out of the realm of node voltage analysis. Use of the supernode is the accepted practice. For example: enjoy-electrical.blogspot.com/2012/05/… | |
| Feb 27, 2013 at 16:28 | comment | added | Shane Yost | That was exactly what I was missing. I was not implementing the last step (V1=V2+12). So how do I dictate when and when not to enter a 3rd equation into a system of equations to solve? | |
