Imagine one wanted to measure the discharge from a Van De Graaff generator using an oscilloscope. The voltages are way beyond what a typical scope and probes can handle. I was thinking about how a voltage divider could be used to make this possible, but I am aware that the overall resistance of the voltage divider circuit would slow down the discharge from the Van De Graaf (since it's effectively a capacitor discharging).
What would be an effective way to measure the discharge from something like this?
PS: I am aware that you can calculate it, as you know the capacitance of the metal dome from its radius, but I'm curious how this is measured.
