High Voltage Probe

This page is the area where I explain some of my projects I am currently working on, as well as those that have been completed in the very recent past but are relevant still. Any questions about them are welcome and can be submitted by way of the feedback page and will be answered in some way or another... Because the commercially made high voltage probes simply do not go above 50,000V ordinarily, I decided to make my own exceedingly high voltage probe to measure voltages such as the discharge of a Tesla coil.

These are two resistors from Ohmite that I plan on using to make a very high voltage probe. Each one is 10GΩ with a 1% rating. They are both built to withstand 10,000V safely.

This is the commercially-made high voltage probe that I own, made by Beckman. It's rated at 50,000 Volts, which is entirely too low for some of what I do. Oddly enough, I was hesitant to rely on the Beckman high voltage probe because it needed an imput impedance of 22MΩ, and I'd end up making multiplicative corrections to the reading on an ordinary 10MΩ input meter. You'd never guess what I found in the piles of old electronics in the back room of the physics E-shop...
