Hi there,
Does anyone know of a machine/equipment/technology, etc. that allows a person to give charges (Coulombs) to conductors in a measurable way? I've rubbed a ton of plastic rods with fur but that's not too measurable. The Van De Graaff is overkill or it if I try to connect alligator clips and wires from the Van De Graaff to where I want the charge to go to, the charge bleeds off really quick. I admit I have not tried a Windhurst machine yet. If you know of something that can scientifically dispense charge (Coulombs), I would definitely appreciate it.
I'm not looking for lethal or dangerous amounts, its just for student projects at college. I'm basically charging up pith balls and hollow, metal spheres a couple inches diameter, and would like to be able to charge such items in a measurable way where the effects of repulsion and attraction are easily seen. The most charge I work with is what a single, lab-demo Van De Graaff can produce so I don't need anymore charge than that. I am certainly not trying to do anything dangerous.
