Hmm, I hadn't thought of that. So, given such a small capacitance value, how on earth do i test it. The small capacitance is not really a problem for me, but being able to measure that value is.

Hello, (my first post) I have a question concerning capacitors. Is it possible to make a capacitor using two metal tubes (one smaller in diameter than the other) made of brass. Both tubes would of course need to be isolated and (if I understand the theory behind capacitors) the inner tub would have to be connected to the voltage source (??). I've tried to make something similar to this, but have thus far, been unsuccessful (my voltmeter's capacitance function gives me no real reading). Thanks.
