this is the most node analysis
i can do , without giving away all
the deeper secrets of equation writing

Extra comments :

writing the initial equations for series analysis requires
KVL +-sign with Ohm's Law +-sign

Writing the Initial equations for parallel node analysis requires
KCL +-sign with ohm's Law +-sign

Much of the time , especially with node equatoin writing,
the ohm's law +-sign is inherently +pos.

That doesn't say it t doesn't exist.
we need to be aware of Ohm's Law +-sign
for loop and node equation writing,
of the initial equaitons.

i avoided ohm's law discussion in this Node video

when we write V = iR we are using ohm's law for
( series loop analysis )

when we write i = V/R we are using ohm's law for
( parallel node analysis )

The Passive Sign convention must be used with hole flow
