How do you analyze a circuit with a short. Here is a simple circuit.
renzoms:
I am familiar with kvl, kcl, thevenin, norton, nodal, mesh, supernode, supermesh, and using kramers rule. I’m getting back into it. So. What do you do when a circuit has a short?
renzoms:
I've got answers. Thank you.
KMoffett:
Please post the answer you arirved at. I may help others in the future. We are here to share solutions to problems.
renzoms:
The compinents on the right can be ignored as the short bridges them. In technicalnterms, the potential on both sides of the components is the same (shorted), therefor the voltage across them is 0V, therefor the do nothing
In case of a short, both nodes at the ends of the short can be considered the same. Voltage at both ends must be equal. In the above schematic, that means no current into the capacitor and resistor on the right, because there is no voltage difference over them.
The capacitor branch has no influence on the circuit because of the short you can just erase it from the schematic and it would be the same (in reality because of the wire resistance you would get a tiny bit of current on the capacitor but almost nothing)

You explanation does not cover the 2 ohm resistor on the right side.
