Hey, I am currious how you guys make electrontics for a car when the voltage can differ by more than 2 volts at any two points in time because a cars voltage can vary from 12-14.5v. just wondering

In these devices are there circuts that measure the amount of voltage and determine the amout of resistance need to be applied to get a certain voltage. thanks again the above stuff was interesting tho
