What is the Electric Resistance of Plaster of Paris?
I am building a Marx HV Generator and I want to make resistors to use and I thought Plaster of paris would be a good material to use as a resistor
I am not going over 200,000 volts or so it will hold up I know that, but but how much resistance is there
Alot of water in there is the whole idea isn’t it? that is why I chose it
1st If it burns it will go out when i take power away
2nd It will not because it is solid and there will be enough to dissipate heat well with all that water
Well, gypsum is a good insulator. Its resistance would depend on what impurities (such as moisture) were present in it.
If you are planning on using this with high voltage, you should be more concerned with the dielectric breakdown voltage than the resistance. This is the voltage at which a material that is normally an insulator will begin to permit electricity to arc through it. Check the link below for more information.
