Okay, just when I think I have something I read it elsewhere and am more confused. See the attached pdfs, Schaums problem 1.15 and even 1.16
Compare to the NCEES problem #4 which I thought I finally got. They seem opposite? Maybe its because of the rearranging?
I posted to the passing zone based on this solution, thought I understood. I don’t think you need the thread but here is the last response.
“First go around the loop and determine the voltage gains and losses by the rules above and find the net voltage source in the loop. Put that voltage on the left side of the equal sign. Next, go around the loop in the same direction. At each resistor, if the current is in the same direction you are going around the loop, add the current times the resistance. If the current is in the opposite direction you are going around the loop, subtract the current times the resistance. Put the current times resistance on the right side of the equal sign.”
You guys have a way of making things clear. How do I assign the polarities at the resistors when none are assigned? Maybe ive been staring at this too long..
Again any help is appreciated.
