What is the actual cause behind this? Wikipedia has such a bullshit explanation
>Regardless of the driving force, the current density is found to be greatest at the conductor's surface, with a reduced magnitude deeper in the conductor.
>is found
And the paragraph above that text in Wikipedia is just made up nonsense
conductive losses and shielding from charge carriers. fields don't penetrate good conductors well, and don't penetrate perfect conductors at all.
so a hollow conductor will have the same or nearly the same conductivity?
>same or nearly the same conductivity?
no according to op it should have more, since there's more surface.
it only applies to the outer surface
maybe this is why thick cables are made of many strands, or maybe thats just for flexibility
It's just for flexibility. Stranded cables are actually lossier because of contact resistance between the strands
stranded cables can carry more AC current than an equivalent solid cable due to skin effect.
a design choice can have multiple benefits.
There's a reason data cables inside your computer are flat, they can't risk resistive losses causing data corruption.
>resistive losses
data lines don't carry much current. they're dealing with signal corruption from cable capacitance or something
Those are just the Eddy Currents.
That's not true at all. Morons just confuse field lines for the actual current flow.
field lines are the actual energy being produced by particle acceleration. the energy is being carried in the field, the electrons are just the particles producing the energy. electricity isn't moving electrons, that's like saying a gun is the bullet
>field lines are the actual energy being produced by particle acceleration.
No it isn't fricktard, it's the field lines. There is zero net energy "production", that's the entire point of charge and energy conservation. The field shows you the effect of the charge (dual) particles can have, it is not a new production decoupled from the position and momentum of the charges, not even in QFT abstractions.
>the energy is being carried in the field, the electrons are just the particles producing the energy. electricity isn't moving electrons, that's like saying a gun is the bullet
Stop letting that midwit Veritasium or whatever his name is rot your brain. You cannot move the field without moving point charges. Furthermore if you imagine a voltage applied to a conductor then your current density will change based on the _cross_-sectional area of the conductor rather than the surface area of the conductor. If it were the latter you would have a point. As it stands you don't.
>Electricity has* a surface phenomenon that occurs on the boundary between conductors and dielectrics.
not true. electricity is a field that doesn't occur in the wire at all.
Waaaooow im going insaaaaane
Mach's principle is universal.
> occurs on the boundary between conductors and dielectrics.
That saves a lot of copper
I think IQfy should master Newtonian mechanics before tackling the mysteries of electrictiy
we need custom captchas that test highschool-level knowledge at minimum
we need these psychobabble OPs destroyed on sight.
too many low-midwit trades people and hobbyists dominate the discourse surrounding electricity so there's too much disinformation to sift through
