Because youre solving the node from v1 to v2 in the superior part And we have these components: 6v, 3 ohms, and 1 ohm And we see the current es going upwords Now we solve: V1-V2.. but in the way we find a voltage that is 6 and it enters in negative.. So V1-V2-6 Now we see we have resistors in the way 3 and 1, we add it up and we know we're gonna divide by the resistors and that's it
@@seto47 no, he isn't. Think about it. Imagine your doing the writing looking into a mirror, not the screen. It's all just witten on glass an filmed through the glass, then reversed with software later.
Your video is excellent and ought to be rated much higher than it is now.
You are an amazing teacher :)
Well explained
Thanks alot
Dan does the same sort of problem, but I like this guy Alex's presentation a lot better as someone who has no familiarity with this.
why did you do nodal analysis without using supernodes for the voltage sources
Lazy and not teaching well.
5:00 why do u add the 6V battery in this equation but subtract it in the first equation at 1:30?
He doesn't.
Thanks - helpful. Though why for the current coming into V1, at 1:39, do you have (v1+6-V2)/4. Why not just (6-V1)/1 or should it be (v1-6)/1.

Don't confuse or involve other wires, he's only doing the superior part, the wire that's at the top and it involves all those components
how do you do mirror writing like that!?
Peyman mohseni kiasari his shirt is mirrord so he is writing normal. And a mirror video eddit

why isnt there a node between the 1 ohm and 6 volts
Being lazy and sloppy , that's why. This would never fly for formal analysis, but hey he didn't even bother to label everything first.
@@veritasiumaequitasius3530 it’s not an essential node
why did u find V1 two times?
once for short circuit once for Open circuit (they are different V1's)
6:31 😂😂😂
By the way very helpful. Thanks 👌
Very sloppy nodal analysis, didn't label things.
very messy
