Do you have an oil in your mind? Basically, the capacitor, which was designed for 5 kV 10 kHz, is expect to work for 10 kV 10 kHz. Another question, if add/change material (oil dielectric or zinc coating or CuO coating or zinc tube), will the signal/frequency transmission be affected (e.g...

Thanks Berkeman, You are right about the Paschen curve. I should say that the vacuum is at the lower end of the curve. (say, an other attempt could be to adjust the vacuum to either a small tor or a higher pressure with an inert gas, if the original vacuum was not at the optional level) I...

Homework Statement You have a co-axial cylindrical capacitor placed in vacuum. The two co-axial cylinder tubes are made of copper. The outside tube radius a1 and inside tube radius a2, with overlapping length L; both tubes have a thickness of t. Say, the capacitor was designed to withstand 5...
