How does current flow in a circuit?

[LarryFine]

One last question about KCL.

In the figure. R = 1 ohm and Vdc = 1 volt

Ix = ???

Looks like a floating neutral to me. I say 0.0a.

In the picture below, where is the start and finsh?

In the same place?

What is a floating neutral?

What is a floating neutral?

When you have your head above water

 

[neutral]

When you have your head above water

I hope it works for other things as well? because I'm always into something deep, :grin: but it smells worse than water and a little thicker seems like lately I'm carrying a heavier load, which makes it hard to stay afloat. Dang those mwbc.

What is a floating neutral?

Seriously? It's so hard to tell sometimes.

It's when the load neutral point is not connected to the source neutral point.


Examples:

Disconnected neutral in a MWBC.

Broken neutral in a service feeder.

(The above are really the same thing.)

Correct.

The start is when you watch the videotape. The finish is a week later.

You got the answer, was there another part?

Initial impression, Ix = 0 (subject to the tolerance of the resistor and their actual values ).

Yes. Ix = 0. Everyone has their own reasons (of why Ix = 0), I got mine (V+=V- on the branch of Ix), they are not same, but either one is fine. Thats the conclussion I got from this thread.

You got the answer, was there another part?

It was not. I believe Im missing something. It was more difficult the last time I did it. :grin:

I have to check. I dont want to start a new discussion on this mivey. I give up. And Im not a woman!!

I guess if you found the equivalent delta last time you would have put in a little more work.

I think someone had a projection problem. :grin:

hahaha. No, I didnt. Thats silly, if I happen to do that I will lost the reference of where Ix is. So it would not be any help.

I believe the circuit was some kind different. I will check on my notes.

I was preventing that you would say to me the same Smart $ said to you at the end of your KCL discussion. "the woman prerogative" part. It was funny, thats a good way to end a two engineers discussion, ...

Sad but true. Maybe I'll send him one of these:
I give up, sorta.

Well, one engineer anyway.

Oh they seem soo nice and comfortable... Probably he would liked those. And there are all sizes.

No bites? I thought it would ring a bell with someone.

Thats a good way to prove when movie is really bad...

Gentlemen,

I have enjoyed this discussion, even though some of the math went beyond me. I did get a lot out of it.

Thanks for a great post

 

[mivey]

...even though some of the math went beyond me.

It is really not that bad. It is just a matter of keeping up with your signs and/or directions. Life is much easier if you have a calculator that handles complex math. Without that, you just have to take a few extra steps.

I posted this summary of the math. Read at your leisure.
