To Fuse or Not to Fuse... That is the question!

herman,


E-field is due to charge differential, which is a factor of electrons everywhere in the circuit all at once. Moving charges, i.e. moving electrons in traditional model or (photons quantum model) leads to magnetic field (b-field). Energy vector is integrated cross-product of e-field and b-field over the whole circuit which points to the load always. The b-field and e-field change direction, but the product of them does not.

So while energy transfer is one way, AC is bidirectional and has different field directions for the electric and magnetic fields.

Charge does move, whether very slow, or what is effectively back and force in one place.

It’s push me, pull me 🔛 plain and simple. The current is alternating on the + and - wires. When the current travels one way on one wire current travels the opposite way on the other wire. You can’t make it any simpler than that. When you switch the + and - wires the speakers operate out of polarity. I agree electrons are a red herring. So are the E and B fields. They are a function of the current. Current is the moving charge.

No, E fields are not a function of current in this example. You can have an E-field without current. You need a changing e-field / current to have a b-field.

You need to stop eating so many red-herrings. It is giving you indigestion.

Uh, but for audio cables there IS current. So your argument is irrelevant. We know there are such things as E and H fields from Heaviside and Poynting. And probably Maxwell, too. Nobody is denying they exist. Remember, just because they’re truisms doesn’t mean they support your position.

And just because you repeat the wrong things over and over that you don't seem to understand does not make them right either.
Saying there is current and ignoring current everywhere in the cable, just like ignoring that the e-field and b-fields change direction, and that they lead to the energy vector and spouting blindly "but but but the energy vector is always towards the load", again, does not make anything you are trying to claim correct. It is not.
