There are no stupid questions, only stupid people.

Sometimes I find it hard to believe that we actually call ourselves
sentient beings with the way some of you act.

The formulas are functions of wire diameter, wire resistivity and
frequency, and do not lose validity merely because a thick wire has AC
resistance greater than DC resistance at a frequency that is easy to label
"NOT high".

The whole point is that it does NOT list the resistances as being
different at that frequency, for that wire, AND it had several digits
shown after the last significant figure given.

That and pumping the numbers through the formula myself with a 20+
mantissa calculator show the same result.

Since a thin round copper wire has a very low emissivity it wont

Ever hear of convection, dumbass?

Got some numbers? Or is this going to be another one of your

This will mean that your thermal
gradient won't be as prevalent as you suggest. The proof is when one
takes a copper wire and places it across a battery's terminals.
Notice how the entire wire turns a nice cherry red quite evenly, all
the way up to where it is attached to any form of sinking element.

---
I see. Just by _looking_ at the glowing wire you can tell what the
temperature differential is between the center of the wire and its
surface? Amazing!!!
---

The current throughout the wire will be even,

---
No, it won't. it'll be lower in the parts of the wire which are
hotter.
---

and it is that current
which generates the heat, or more precisely, the resistance to said
current flow.

---
The current changes the temperature of the wire, but it doesn't
generate the resistance of the wire. The wire's resistance and its
temperature coefficient of resistance are due to the resistivity and
tempco of the material the wire is made of.
---

If the wire were giving up its heat real fast, like that of a finned
heat sink with air passing over it, I might agree.

---
Whether you agree or not is immaterial. The phenomenon occurs with
or without your permission.
---

In the case of
bare copper, however, the temperature throughout the wire is going to
be very even. Your gradient will be nearly undetectable.

---
Point is, dimwit, it'll still be there.
---

For a very large diameter copper bus, it MIGHT have a slight
gradient between the center and the outer surface, but not much. For
wire, it is as even as even gets.

Got some numbers, or is that just some more of your bullshit
opinion?

"Corona discharge" is *NOT* caused by AC or skin effect. Corona discharge
is caused by a high voltage gradient in the space around a conductor.
This
is a combination of the voltage applied to the conductor and the effective
radius of the conductor. A high voltage, or very small effective radius
can
increase the gradient to the point where the air is ionized. Simple proof
is that corona discharge is a problem with high DC voltage systems as well
as AC.

Sometimes hollow tubes are used for high frequency power conductors. This
reduces the weight and cost by eliminating the central part of the
conductor, where 'skin effect' has rendered the impedence high anyway. So
little admittance is lost for a great savings in material/weight.

VERY high frequency. NOT AC line frequencies.


Not so. I could show you several switchyards within a short drive that use
many hollow tube conductors all over the yard.

daestrom

I thought large diameter conductors in switchyards were for corona
reduction.
---------
Not directly related, an engineering handbook lists the skin effect for
a 500MCM conductor as increasing the resistance by 2% - which I would
say is significant.
-----------
Since TokaMundo is infallable, consider the possibiltiy that he is
actually the pope. He has also been identified as a troll.

Going by "High Frequency Resistance", pages 3323-3325 of the 43rd
edition of the "CRC Handbook":

They give a formula X=pi*d*SQR((2*u*f)/rho)*SQR(1000)

u is magnetic permeability, unity for copper.

rho is resistivity in microohm-cm.

They simplify this for copper, to x=10*d*.01071SQR(f)

d is diameter in centimeters, and f is frequency in Hz.

So, for 17 mm diameter copper wire at 60 Hz this "x" is 1.41.

Next is a table that gives ratio of AC resistance to DC resistance as a
function of this "x".

This table has an entry for 1.4, giving AC resistance 1.020 times DC
resistance.


The table I saw shows the AC and DC resistance as being exactly the
same for both.

Your flaw is where you failed to note the topic given in the CRC
handbook.

60 Hz is NOT high frequency... at all.

Try some calculations at 100 kHz and you'll see that those
frequencies down near zero (ie 60Hz) yield very nearly nil difference.

What is a high frequency?
If this is not defined in the source, then most of the time a high frequency
will be any frequency on what the voltage on the line cannot be taken equal
at every place of the line because of linelength and wavelength.
By this 60Hz can be a very high frequency if you have a cable of several
kilometers.

Yours certainly contributed absofuckinglutely nothing, and would
certainly fall into the "stupid answer" category.

You remind me of a Firesign Theatre quote:

"Who wona second world war.. you so smart?"

Perhaps, if you are so informed, you should try giving an answer
that actually has facts in it that are in sync with the topic of the
thread, not merely its title.

Someone once tolf me something, I believe it wass: "Don't feed the trolls",
it seems to me that they are having a ball with food in abundance.
