For the record, VrmsP on Rigol scopes means Vrms across 1 period (cycle), so NOT the "rms value of the phase voltage"
i mentioned above (thats another animal).

Most scopes call it CycVrms or Vrms cycle.

Normally used Vrms is taken from the whole display/record of the scope.

Seems the HELP function on the Rigol scope will show this info, not the manual.

Thanks again guys, indeed the help menu of rigol is very helpfull. I have the tendency to forget about it

Interesting paper but if we do the math, we understand why electron inertia is possibly negligible.
Imagine a 1A current in a circuit, this means 1 Coulomb/second, i.e 6 250 000 000 000 000 000 electrons/s. This number seems enormous but if you calculate the mass passing each second, the electron mass being 9.11x10^-31Kg, it is only 0,00000000000569375 Kg/s.

Could this extremely weak mass have an effect on acceleration? I had recently calculated the electrons acceleration in a CRT, say V=30 KV and d=40 cm between cathode and anode:
E= 30/0.4 = 75 KV/m,  F = m*a = q*E => a = q*E/m
a = 1,6 * 10^-19 * 75 * 10^3 / 9,1 × 10⁻³¹
a = 13 186 813 186 813 186 m/s²: this is a so tremendous acceleration that it's obvious we have to re-calculate using relativistic corrections.

But in a conductor where the electron drift velocity is extremely slow (<< 1mm/s), the acceleration should be negligible.
Now we must not forget that the electron drift velocity is only an average, there are many collisions in the metal lattice that stop the electron and huge accelerations in between. So I have not the definite answer.

I don't think even particle physicists and quantum physicists agree on material particles and if light travels or not
