Hello from the Swiss (with repaired mitral valve)
I would like to represent electric current (non compressible) by little spheres moving in a tube. A resistance will be represented by a bottleneck in the middle of the tube. The whole system must be totally filled with particles at staring point.
When the particles are 'pushed' (emitted) from the left, all particles should move without overlapping to the right (and then be killed). I tried different methods (even fluid sim)... but no good result. What system is the easiest to realize this.

Bon Giorno, Henri!
We can exclude this version, but I will share it to get more feedback.
Here is a sketch with a "package" of spheres that moves based on a force field, accelerates in the bottleneck, and slows down. (Do I memorize this correctly from my two-year education in electricity/electronics? It is four decades back in time.)
You can change the speed in the Force Field> Spline. direction > Layer
The killing of electrons needs a trick: the move (eyeballing) of the "Linear Field".
Going by your description, the first and last frames might not be helpful.
Let me know if that works for you.
Hello signore Sassi
You are incredible! ANel is technically what I was looking for. I needed some time to understand what you did. I will not exclude this version. This solution is fast, gives a realistic visualization of the electron flow.
Now I have to work on this, to make a closed circuit with this b-spline (coming out of a cube(source)... passing the bottleneck ... and going back to the source on a parallel line, to close the circuit.
I expected a solution with thinking particles... but this blowed my mind.
I will keep you informed.

Thanks a lot for the feedback, Henri.
The first one uses short comping of splines and animation to its advantage, such that the distance between points is crucial for the speed.
The Force Field has a lot of potential, and adjusting the "force" along a spline is very powerful.
More about Force Field can be found on our team's many shows over on YouTube.
Let me know if there is anything else. I have some time off (Holiday here), but, of course, I have an eye on the forum.
My best wishes for your project
