I have a few questions about using automobile ignition coils and drawing arcs...
As I understand it ignition coils are not "true" transformers. They are made to function with DC and therefore need interruption in the form of a manual (relay) or IC (a 555 chip) to display any arc. Is this the case or could AC be used?
The design is one of high current input; what would result from high voltage & low current to the out put (& displayed arc/spark)?
The purpose of a capacitor (condenser) would be to allow the spark to "halt & perhaps filter" momentarily and to limit the wear of the contacts.....is there any formula on it's design? I believe that .1uF would be enough to accomplish this. Am I incorrect?
Seeing as they are oil filled, I would imagine they are tough but to what level? I that I would want to make a small display of their spark making ability; what would be some of the limits of their power handling ability?
Thanks in advance: I know this is a lot of material but I am wondering if anyone has experimented with them & their observations.
