High Current or High Voltage that damages components?
1) For example if you have a working circuit with a 10V battery, fixed 5 Ohms resistance and a current of 2A. If you then swap that battery to 20V, would it be the new current of 4A that does the damage or that fact that the voltage is now 20V? Both values are higher than they should be so which factor will do the damage, both?
battery
What had happened was my Volt Regulator, that regulates how many volts run through your car, went bad. I had boosted and jump started my battery over 30 times, I knew it wasn''t the alternator because in the 90s they didn''t have the regulator in the alternator and if it was the Alternator the car would run dead on the road.
