How electricity moves through wires

webberfolds

yes I know about that principal. Electrical current behaves like a fluid but it depends on what is meant by fluid, thanks. I wasn't comparing electrical current to race cars and if i said electrical current i meant the one that's almost the speed of light. What's a good word for it? I know now that I shouldn't be calling it electrical current but electricity seems to be confusing. Thanks.

webberfolds, moving racecars affect each mostly through the Bernoulli's principle.

Now whether Bernoulli's principle can be applied to electrical current, well is it a fluid?

So the electric field causes a lot more current than the magnetic field in this picture? What if the electric and magnetic fields swapped places? So do the purple arrows represent the velocity of the current? V=d*E, V is the voltage between what points? "E" is the strength of the electric field where? Thanks, I'm understanding more and more of it.

The higher the current, the longer the arrow.
If you look at any point along the line on z direction, the EM wave moving at almost the speed of light, so one incident, the wave is at it's peak, a moment later, it's at 0 point. The surface current change accordingly, so if you measure the voltage at one fixed point, you see the change in the E field which give the voltage where V=d*E in this case. d is the separation between the bottom and the top plate as shown in the diagram.
