'all im saying is if you "dont know" or "dont understand'
No YOU are the one who does not understand.
a VOLTAGE VOLTAGE VOLTAGE VOLTAGE VOLTAGE regulator regulates SYSTEM VOLTAGE, period END of story.
The fact that it changes, modulates, adjusts field CURRENT is an INTERNAL function of the regulating loop. It does NOT change system OUTPUT current The changing RESISTANCE of the system itself is what causes current change.
You do not seem to understand that concept. The fact that field current is changing does NOT MAKE THIS a "current" arguement.
Worse your "analysis" of what happens to the human body is INCORRECT. Yes, it is true that a certain amount of current flow is what endangers, damages, or kills a human, but there has to be enough VOLTAGE to CAUSE this current to flow depending on the body RESISTANCE
There, I've just defined the basis of Ohms Law. More voltage across a specific resistance causes more current flow. Change any one of the three, and at least one other MUST change.
In this case ( VOLTAGE REGULATOR) we have made VOLTAGE a constant. What that means is, in order to cause a change in CURRENT flow we must change system RESISTANCE, IE the state of charge of the battery, or the other LOADS on the system, such as lights, heater, etc. As the LOADS on the system change, the VOLTAGE regulator senses a sag in system voltage BECAUSE of the change in current and LOAD, and ramps up the voltage to KEEP THE VOLTAGE CONSTANT
More voltage in an ignition system does NOT mean a hotter spark, either, l UNLESS the "improved" ignition system can SOURCE THE CURRENT to MAINTAIN that high voltage.
My the same comparison, an alternator could not maintain it's voltage as controlled by the regulator, unless the alternator can source the maximum current required.
The comparison here would be to add a string of AAA cells, as compared to some nice big D cells. The current capacity of the AAA cells is low compared to the D cells. IT would do you no good to add a bunch of AAA cells in a system to increase voltage IF THE LOAD CURRENT exceeded their capacity.
