All capacitors are measures in micro-farads, a single farad is an huge amount of electrical charge, As I recall the definition of a farad is the capacitance of a capacitor of which a potential of 1 volt is created by a charge of one coulomb. And since this is an SI unit, the plates would have to be 1 metre square, and 1 metre apart. We are talking big. Dan. > imc >
