Some useless but maybe interesting comments: Michael Faraday discovered that current in one coil would induce current in another coil nearby. I don"t have the dates exactly, but I think it was around 1830. A few years earlier, another researcher, a Dane named Oersted, accidentally discovered that a current in a wire creates a field around the wire (he noticed that bringing a compass near to the wire caused the needle to move)(Uri Geller tried to show that he could do the same thing using his magical powers; turns out he used tiny magnets). Faraday took up where Oersted had left off. The farad is named for Faraday. Other useless information: the original condensers were big glass jars (Leyden jars)lined inside and out with foil. Static-electricity generators fed current to each side of the glass. When the current was released, there could be quite a jolt. Seems it was a parlor trick in the late 1700s to shock your guests with current in a Leyden jar.
Other terms named for individuals: Ohm and ampere. Poor Mr. Oersted apparently didn"t get anything named for him. Some of the writers answering say that the ignition system will work without a condenser. I have seen engines--way back when--that wouldn"t run when the condenser failed. Has anyone seen an engine run without a condenser? Perhaps with a very wide gap, to make it hard for the current to jump the gap?
The condenser certainly has the function of keeping the points from burning (because the electrical current "wants" to keep going across the gap and will make a considerable spark without a condenser to absorb the current briefly), but it is also true that if the current continues across the points, there will not be much of a breakdown in the magnetic field across the secondary winding of the coil, hence a very weak or maybe even no spark. Hope I"m not repeating what others have said.

Today's Featured Article - Women and Tractors - Tractor Engine Repair - by Teri Burkholder. One of the great things about working on a tractor engine with your other half is that you know what he is thinking of at all times and can anticipate his every move and his next thought of what he will do. With Ben, anyway, I can tell! He'll be busy working and I’m handing him tools and he says, "give me that..." and I’ve already got it in his hand or "hand me that....."and I’ve got the portable light right where he needed it placed to see. "Run in the house and get me a...."as I open th
