I want to understand why the reaction force of the short cable and link cable is in this direction? I want to understand it instead of memorizing. Your help would be much appreciated. Thanks in advance!

i want to know the size of a k-map. How many rows and how many columns and cells?

Oh got it. Thanks, appreciated.

In node analysis, after labeling the nodes. I don't know how to choose currents direction to apply KCL. it seems too complicated.. and I end up every time getting different answers the the solution sheet. I've an exam tomorrow. would be much appreciated if you could help me better understand the...

no i don't know why it isn't.

if you take a close look, you would see he took 18 parallel with 9 ohms and found their equivalent resistance.

it isn't a homework though.

Yes I'm uploading it. give me one minute

< Mentor Note -- thread moved to HH from the technical physics forums, so no HH Template is shown >[/color] in the solution sheet, He took the 18 ohms parallel with the 9 ohms and not the 6 ohms. I don't understand why he took this approach. I was going to take 18 ohms parallel with the 6 ohms...

Got it. Thank you, appreciated.

So you mean if the current doesn't go anywhere after passing through the resistor so we disregard it? we consider the current is equal 0?

it will go to V0. there is a voltage V0

I don't know the current through that resistor. Actually I don't know the current on any of the resistors so I'm not sure what you are trying to say.

I want to know why in this problem in the solution, he disregarded the 1 ohm resistor and found the equivalent resistance of 6 and 3 ohms right away. https://imgur.com/a/efG11

Here the voltage is negative so the current is negative. does it matter if I traverse the circuit through the other direction?
