Hi,
Is A an essential Node though?Hi,
Did you write (15-C)/1k ?
I dont think you can do that i think you have to write (A-C)/1k for that current because you dont know what A is yet.
Hi,Is A an essential Node though?
You are getting really sloppy and making a bunch of mistakes.
Whether a node is an essential node has nothing to do with what you are calculating. An essential node is any node that has more than two branches connected to it. This problem has four essential nodes. Since you get to arbitrarily pick the voltage on one node, you need to write node equations for the other three (thus matching the number of mesh equations you would need to write).Hi,
Well it depends on what you are calculating, and it looks like you need to calculate the node A too right?
