Hi Gert and the group, I am careful not to handle these resistors to keep from having my skin chemicals contaminate the surface of the resistors and possibly change their value. They are a lot of fun to play around with in the lab.
Many times it is dangerous to send your equipment out for calibration. I have lost count of the number of times it came back damaged in one way or another. So for my friends with resistance meters used in static compliance measurements of things like workstations, I tell them to buy a bunch of these resistors to calibrate their instruments and just send the resistors to the cal labs to be checked!

In the 80-ties i have been involved in operational amplifiers for gas chromatographes, or actually parametric amplifiers as they were called at the time. We used resistors in this range. Note you cannot mount them on a Printed Circuit board, but need to apply teflon stand-ups, hat need to be washed ultrasonically before testing. I still have some (glass) samples about 5cm long. On 13-8-2025 21:51, John Woodgate wrote: Coaxial power cables are indeed used for this purpose. But I developed a method of measuring the current in the cable without cutting it, by measuring the magnitude of the residual magnetic field. It was taken seriously by a research scientist, but that didn't result in further progress, as far as I know. The reason I did this work is that hearing loops use audio-frequency magnetic fields in the microtesla range, so I know how to measure them. If anyone is interested in the idea, please send me an email. It doesn't work for DC, of course, without some trickery.

To address dielectric effects, I have seen both cables and capacitors “recharge” themselves to some extent after being discharged. I have a large (I can barely lift it) 50,000 Volt capacitor that I keep a 1 GOhm resistor across it that would discharge it over a few minutes after my experiments if I forget to reinstall the short after using it. The time constant is long enough not to affect my experiments which usually only need it to be charged for a few seconds. You can get 100MOhm to 10 GOhm UxCell brand resistors from Amazon.

Rinsing it a sufficient amplitude DC will iron out the storage, and make the cable suitable for its purpose. Everytime i drink a beer the mechanisme shows crystal clear, the day after its gone ....

Do you mean stored charge in the dielectric? I suppose that if the cable is non-uniform, either due to construction of damage in usage, there might be separated charges in different places along the cable? I can't see that any alternating voltages or currents could occur.
