Silly question Stuart, but I have to ask  - Mag loop users will have noticed
the phenomena of extremely high voltages across the loop capacitor - hence
the need for high-voltage capacitors when high powers (greater than 20-50
W ) are poured into the system. How do you reconcile that high-voltage with
the "conventional wisdom" of the need for low resistance to achieve high
current.
