[volt-nuts] Small capacitance

[Will]

Extremely low value (3 terminal!) standard capacitors are usually
constructed using a metal plate (guard) with a small aperture hole in
center and two parallell metal plates (the capacitor) on both sides of
the guard. The capacitance is adjusted by changing the distance of the
plates and the size of the aperture.
