???? Capacitance in a coil? The basic ingredients of a capacitor are two
conductors seperated by an insulator ---||---
A coil of wire on the other hand is just one long conductor. It may have
a lot of inductance, but I can't see it having much capacitance (or are
you talking about a two cored cable? Even then there would only be a
small amount between the cores).
