Re: [EVGRAY] Cap charging and use

Body

James,

This is an interesting way of going about it, with high voltage often
caps are used in voltage divider networks instead of resistors.  Good idea!

The only problem is the larger caps are usually lower voltage else very
expensive and the lower voltage caps can be damaged by the initial pulse
prior to charge diffusion even though the voltage does go lower based on
the larger farad capacity.
