Re: [TCML] voltage divider

["Peter Terren" <pterren@xxxxxxxxxxxx>]

Here is my water resistor which is about 6 feet long and currently is set 
for 200K with a very dilute solution of copper sulphate.  It can be refilled 
with a much higher impedance and with deionised water should be able to go 
into the 1GOhm range where it may be useful as a low capacitance, low 
inductance resistive divider. Tapped at 1000:1 might be Ok to run a CRO, but 
I haven't used it for TC work.  I mostly use it for high power, high voltage 
resistive ballast for a big x-ray transformer to draw out 24inch arcs.
