charging current if the battery is on its own, but what if a random
changing load is connected, as there is in a running car?
The voltage perhaps.
Definitely. One of the simplest ways to msake a vcarger is to have a
constant voltage source in series with somem form of resistor. As the
terminal voltage rises so too does the charge current drop.
The problem that brings is when a heavy cirrent is siltanoeusly drawn
from the battery.
Which is why car alternator control is a little more spohisticated than
that.
