Sorry about the intrusion as I really don't belong here as I have absolutely no background in physics but I have a couple of questions regarding lead acid batteries that I have been unable to find answers to on the internet.
First question - why does a battery spark/arc when the negative is hooked directly up to the positive. I had thought that the electron imbalance on the cathode was seeking to balance out by "getting" to the anode and it seems that hooking up the cathode directly to the anode would most easily satisfy this imbalance.
Second question - When the anode is grounded to a vehicle chassis how do the electrons get from the cathode to the anode to balance the battery. Do they flow through the circuit, power the load and then return through the metal of the chassis? And if so how does the metal of the chassis not become polarized by the charge of the electrons as they move through it? Or are the electrons just moving through a field around the chassis to return to the anode. Very confusing! Can anyone give me a good explanation.
Thanks,
Scott
