Hi Daniel,

The "power factor" is normally the SIN of the angular difference between the voltage and current sine waves in a steady state system. A Tesla coil is not very steady state at all so the power factor varies over time and may lack any real meaning.

Pure inductors and capacitors have very low power factors since the voltage and current waveforms are out of phase by 90 degrees (SIN(90) = 0).

Terry, I think you mean cos(theta)... sin(90) = 1, cos(90)=0

=> YEP!! :o) - Terry <=
