volker@muehlhaus answered the question very detailed. But you seem to adhere to the idea that a low frequency signal with a free space wavelength of 1 km, can't exist in a small circuit.how do you generate a sin wave 100khz in small circuit?
Please imagin this problem.
when sine wave propagate in circuit need Physical distance to propagate.
i ask you read wavelenght theory.
My problem in 10cm physical distance how propagate 1 km distance?

In circuit we have currents and voltages. AC current flow through wire conductor let's say with speed of ligth. On 10cm target it will arrive after 33.333ps at the end of 1km wire it will arrive after delay of 3.333us. After it arrive on target it behaves like ordinary sine wave started at t=0.
from physics s=v*t
path equals speed*time
there must be conductive path between two points for current to flow in between
when you speack about wavelenght the wavelenght means :The covered distance by electron charge to complete one period.
wavelength means: V/F and in space C/F so wavelength is there on conductor.What you consider as wavelength is a period of sine wave current. It is measured in seconds not meters. X axis on diagram is t time and not distance.
We have also a AC voltage that stays in place and does not travel or flow. AC voltage has also it's frequency and wave length the same 300kHz and 1km.
We are not talking about electromagnetic waves what you are confusing with currents or voltages in a 10cm circuit.
Even nowadays it is not known what are electromagnetic waves made from. We know how to make them while physics behind is still to be discovered.
yes voltage not move but current move like domino.
But it is the distance traveled is it true
Energy still exists. Does it have corpuscular or wave nature or something else is still to be discovered. You may call it as ether.
That's complete nonsense.
You start from a wrong concept (wavelength = travel distance for electrons) and that is why all conclusions are wrong.
No, wrong.
you say ac has a period in time and distance.where is the distance in circuit? ??
As discussed above many times: No distance is needed. If the distance is zero, then you only see a change of voltage/current over time. And if there is a distance, the voltage/current at these locations have some time delay. The time delay can be anything from 0 to infinity, depending on distance.
If distance on conductor have same value of wavelength time delay happen because time neded to complete one period is the same with time to propagte this distance.
And when wavelenght very big from length of conductor the delay not happen.
Because distance in this case means sum of electron charge traveled .if your distance 10 cm and wavelength 1 kilometer the time to propagate in 10 cm very very less than time to complete period and in period the sum of traveled 10 cm is 1kilometer because in time period, charge electron can backward and forward 100000 times and asum of this times is 1 kilometer.
