coil discharge.. a coil discharge voltage is based on the resistance of the discharge path. The higher the resistance, the higher the voltage will be.
Increasing the resistance will increase the voltage. Once the voltage is high enough to overcome the resistance or gap, the coil will discharge. Making the voltage higher means it will jump a bigger gap or fire through a simi fouled plug. This works up till the voltage is high enough to overcome the insulation of the coil and short across internally or across the plastic output of the coil, as many coils will do, with no wire hooked to them.
Air has resistance. In a vacuum, it takes less voltage to jump a gap. As pressure increases, in take more voltage to jump the same gap.
changing to carbon wires or resistor plugs can increase the voltage and give you a """hotter""" spark potential. Adding an air gap will also do this. Remember however once the voltage is high enough to jump the gap, its going to fire/arc/discharge at that point and not go any higher. So a good plug will fire at a lower voltage than a bad plug.
A shorted plug will simply drain off the charge through its alternate path,, and not jump any gap and therefore produce no spark to fire off the gasolene.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
