Default Re: Condenser Capacitiance.

Not sure if it is me or you but someone has confused the shit out of this. In a 12 volt ignition system a resistor is added to limit current. That resistor will give off heat so energy is split between that and the coil. If you have a 2ohm coil it will flow 3 amps in a 6 volt system and 6 amps if you put the full 12 volts to it. That is the theory anyway. Other factors may change numbers slightly. Think of a water pipe with 30psi pressure. When you turn on the valve it will flow a certain amount of water and the dynamic pressure may change depending on the source. If you increase the pressure to 60 psi it will flow twice a smuch water given other values remain the same. It might not really be twice as much bit I'm using that for this argument. The points can probably handle 10 amps because they are just contacts. all they care about is how much current goes through them. When the current gets high enough it will create heat in them much like any wire that is not sized big enough for the circuit it is on. A short circuit has no resistance and will flow as many amps as possible. Forcing too many through a small wire creates heat and burns stuff up or down. This is why you need heavy wires on a starte motor. It creates a short until it starts spinning. But that's a complicated subject for another day.
