Of course,final voltage will be lower due to losses,but you are forgetting that SPACE charge around toroid will contribute to voltage situation as well. In other words,part of discharging energy is dissipated in form of heat,electrochemical compounds and sound waves,and other part to build up of static charge around toroid. Very drastical clamping of voltage you are thinking of may occur perhaps when couupling is very low (say<0.1) ---- > One way or another, we're accumulating quite a few > reasonable > candidate explanations here - for lots of different > types of racing > arcs.

I'm still thinking about racing sparks on Bart's coil. regards, Boris __________________________________________________ Do You Yahoo!? LAUNCH - Your Yahoo! Music Experience http://launch.yahoo.com
