Congratulations to everyone, lots of fun n time on such a SIMPLE OBVIOUS question
The obvious answer is Current through the COIL is I = V/R but no one could give an answer UNLESS THE COILS RESISTANCE IS KNOWN !!!!
The Current at any given time is 6 Volts/Coils Resistance at that point in time. If the coils resistance changes with time or temperature so does the current WELL DUH
In some older car coils there were encased in the bottom of the can temperature compensating discrete stand alone resistors (thermistors). Later year standard external ignition ballast resistors (like on all the old farm tractors Ive seen) were more like simple standard resistors, carbon or wire wound, that dropped approximately 6 volts leaving 6 for a 6 volt coil another WELL DUH Im sure everyone here knows that
I DO NOT think the coil George pictured and asked about is one like old cars used as shown and explained in the pictures below, I DO NOT think it, his coil ALONE (His question asked about current when 6 volts was applied to the COIL) (NOT having one of the temp compensating resistors inside) operates the same as the old car coils with internal temp compensating resistors, although sure as temp increases even a modern coils regular wire windings resistance changes slightly NOT AS MUCH AS THE OLD CAR COIL BELOW WITH ITS TEMP COMPENSATION RESISTIOR INSIDE
REGARDLESS the CORRECT answer to what the current is with 6 volts applied to the COIL remains I = 6/R
Fun thread keep em coming neighbor George
I hope this helps explain things and answers the fun question !!!!!!!!!

Today's Featured Article - Tuning-Up Your Tractor: Plugs & Compression Testing - by Curtis Von Fange. The engine seems to run rough. In the exhaust you can hear an occasion 'poofing' sound like somethings not firing on all cylinders. Under loaded conditions the tractor seems to lack power and it belches black smoke out of the exhaust. For some reason it just doesn't want to start up without cranking and cranking the starter. All these conditions can be signals that your unit is in need of a tune up. Ok, so what is involved in a tune up? You say, swap plugs and file the points....now tha
