A physics / electrical / philosophical question.....

formatting link
is my crude drawing of a swimming pool. There are four wires hanging in the pool. L1 and N1 are live and neutral from an isolating transformer. L2 and N2 are live and neutral from another isolating transformer. Both are identical transformers. If you turn ONE of them on, then the current obviously flows diagonally across the pool. But what if you turned both on? Do they care whose electrons they get back? Can't electricity flow across the two short ends of the pool to lower the resistance? If not why not?

Assuming your isolating transformers are perfect and have no capacitive reactance between windings then there will be zero interaction between the two circuits. PS You really need to use the occasional line break.

on the corner shouting at the cars that went by.

If the wires N1 and L2 were connected and L1 and N2 ditto, there would obviously a dead short on the sum of voltages which are in-phase and additive. So the first premise is correct.

If we replace the swimming pool with a set of resistors (6 should be adequate to model the various possible current paths), and the transformers with a pair of batteries, does that change your answer?

That's one of the less annoying habits of the OP...

Now I've got two conflicting answers.....

On mine it wraps to window :-P But let's not start that AGAIN!

I think Clive was really referring to your lack of use of new paragraphs. A big block of text is intimidating and relatively difficult to read. If you're asking for advice, it's courteous to make your question easy to read.

I thing Graham was. I was referring to the fact that the OP is more than a bit of a nob. Hang around, you'll observe this.

I disagree with a lot of opinions, that doesn't make me a nob.

Agreed - but I didn't think I'd typed enough to warrant two paragraphs.

Possibly because they use pulsed stimulation from high source impedance drivers and the pulses are not simultaneously present on the multiple outputs.

If you completed your diagram by including the secondary windings on each transformer outside the pool i.e. between L1 and N1, and L2 and N2 respectively, and bearing in mind that in any circuit, electrons go round in a loop, in this case from L1 across the pool to N1 and then back through the winding to L1 again, ditto L2 and N2, then you can see that the two circuits are separate and electrons won't travel from L1 to N2.

You missed out the loop involving both secondary windings and the short paths through the pool. L1->N2->L2->N1->L1.

Ah..... that makes sense. Thanks.

In another words, you'd get a tingle no matter where you were in the pool!

No I'm not planning on zapping a load of people, honest!

When viewed in Thunderbird your posts do indeed wrap to my window, however large I make it, even stretched across my two monitor extended desktop.

When viewed on my usual newsreader, Forte Agent, your entire post appears as a single line and I have to scroll across to read it.

I am sure I don't have this issue with other Opera users, is there a setting for the maximum length of a line? Failing that you could try hitting the return key once in a while.

You probably don't. The OP is a nob, he has known about the problem for years, many people have pointed out the error of his ways, he's refused to do anything about it.

I use MT-NewsWatcher and have no trouble at all; it wraps to the window.

Why doesn't Our Graham get a better newsreader?

Indeed - Forte is very clunky.
