I  measured nothing.
And even if I measure current ,how to measure top volts to determine what efficiency factors enter the formula?
How did you and others found factor of 0.7 for a typical spark gap tesla coil?

Hi Dex,

Moderators are not going to change an equation. They may later reply and 
correct it with a reply, but they don't need to be messing with a 
persons equation (what is obvious is subjective to how much attention is 
being paid to the equation). Their looking for more of content as it 
relates to the TCML and not necessarily every calculation detail.

DC's equation as you state is a standard energy equation that has been 
around forever. What DC is doing is showing are losses with the 
efficiency factor of 0.7. The same equation is derived with the 
capacitances as well. Your equation is dependent on di/dt. Have you 
measured this yet? If yes, what was the change in current and over what 
time frame (0 to peak). May as well state L also. This equation requires 
measurement to verify, so I can't go any further without some data if 
you have it.

Take care,
Bart
