True, but charge has a force characteristic. The electron has a charge
of -1, or, the value of negative charge carried by an electron is one. A
coulomb is (6.281 times 10 to the 18th power) times the charge carried
by one electron. A coulomb per second past a particular point is also
one ampere.

I have long thought that electrical charges, individually, likely have
random motions but that an ampere is the net result of more charges
moving one way than another.

With so many small charges involved in a net substantial charge flow,
why shouldn`t charges be moving in two or more directions at once?

I believe; I'll tell you. Let me say in terms you might get this time:
The same infinitesimal charge dQ cannot move in two directions
at the same time. In order to do that it would have to split in two
and that would violate the principle of conservation of charge.

Get real, Tom. Does your vehicle battery hold a charge? Is that charge
an infinitesimal point charge? Introducing an infinitesimal charge into
the argument at this late point is known in logic as diverting the issue.

The charge on your battery is a total charge. The charge in a
transmission
line is a total charge. The charge of the planet earth is a total charge.
Charge is moving in opposite directions 1/2WL apart in a transmission
line.
Charge is NOT limited to an infinitesimal charged particle, as you imply.
Charge is a characteristic of *any* number of particles in *any*
magnitude
of volume including, presumably, the entire universe.

Go back to bed, Cecil.

I love it when you wax technical, Tom. :-)

The simplest answer is that charges move in response to the local
electric field they experience. That field has only one value at that
point, at that instant, and is determined by the superposition of all
local electric fields.

If you presume the simplest answer, it still entails complexity in
that this is more correctly called "directed drift" wherein the motion
of the chargeS are random within a locality, but in the aggregate and
as an average tend in one direction.

This sort of dovetails with recent postings by Art speculating about
charge accelerating (without needing power mind you) in the circle of
a loop antenna. The truth of the matter is that those electrons/holes
would never move in a circle, nor even an arc given the short distance
of the net migration being very much less than the diameter of a
small, small wire (and at any HF frequency, infinitesimal).

Hi Jim, we missed you.

For RF, it is certainly possible for the network charges, at t(x), to
be moving in the opposite direction from force exerted by the network
electric field (voltage) at t(x). Remember, dQ/dt can have a different
sign from the sign of the electric field voltage. This ain't DC.

Speaking of pages, there is a nice picture of Yuri Blanarovich, VE3BMV
(formerly OK5BU) on page 81 of the March 1973 edition of CQ magazine.

Many of us may have made a nice picture in 1973.

Thank you kindly. We were young and handsome, now just.... :-)
There is the CQ Magazine cover boy also at

Brings back memories, before I had the job after landing in VE3 I went for my
license, before I furnished the apartment, I bought FTDX400. The first vacation
when I took off for expedition to FP8, I got "stuck" in NYC, met my sweethard,
got engaged in 3 weeks. The rest is history - first, Big Bertha and then couple
of kids and move to the Land of Free and Home of the Brave.

Sorry about delay, had hard drive crash, slowly recovering.

We should change the subject, or W8JI will take credit for it :-)

Mechanical packaging done, also simpler version of Baby DRone is done, I am
putting picture of it on the web. Farming out the cases and PS manufacturing.
Working on fine tuning the architecture and gathering requirements for
features. Had SM5BSZ of Linrad fame here and did some work on circuit design.
Coming along nicely. Just had hard drive crash (IBM) after telling everybody to
back up, while being lazy to do it myself. :-(
Enjoying working with nuts and volts, they don't argue with me, just some times
don't work as they supposed to, but that usually can be fixed while some people
have much higher resistance (or loss :-)
Stay tuned, coming soon to your shack.
