The interesting thing here is that in a half watt resistor of 500,000 mega ohms, the current must be less that 1 micro amps and that would be at a voltage of 500,000 volts. That resistor would need to be longer than a couple of inches to prevent it for arcing around the outside and as someone said in a glass vacuum chamber.
So curiosity has me. Maybe I missed it, but what is its intended use. If for a high voltage meter for measuring static charge, I bet a 0-1 micro amp movement will cost more than your gasoline bill.
