That's what I thought. How can a low impedence increase voltage? Can
you explain Gilly's idea to me?



'Fraid not, but I'll have a guess... :-)

With a parallel cct, Z either side of resonance is low, which would develop
a lower voltage across the two components. The series cct presents high Z
either side of resonance. IOW, the high voltage developed across each
component in the series cct is outside the tuned frequency - at low F on one
component, high F on the other.

Alternatively, and I really am guessing here - how about something to do
with phase effects at resonance? All that leading and lagging of current WRT
voltage.


As far as I understand it, the voltage is just the current times the
impedence. Similarly, the current is only produced by the driver (Vin)
so how can Vout be bigger than Vin (there's no mention of a transformer)?
