No, don't call the patent attorney. Your measurements are probably
erroneous because of the way you are measuring current and voltage. We
do know what you are putting into the circuit, assuming you are measuring
the 11 Amp current as RMS with a "true rms" meter:
120 V (rms) -at- 11 A (rms) = 1320 VA (rms)
These mesaurements are easy to make with a scope or true rms DMM, etc..
since the wave is sinusoidal. Now, for the RF non-sinusoidal input to
the coil itself, you have to also measure amps and volts as RMS. It's
best to do with a scope and the required calculus to find the RMS of the
waveform. Chances are that your waveform exceeds the frequency range in
which a "True RMS" multimeter will give meaningful results. What freq.
range are you operating in, BTW?
Perhaps you could tell us how you measured the 700mA and 3800 volts, so
that we may better serve you?
