I snipped a lot off of this thread and I know all this is a bit off
topic but...
I started fooling around with batteries and motors and all sorts of
stuff I could find in toys back in 1970 at a tender age of 8 years.
A circuit first made sense to me at 6 years old but I had a bit of
trouble learning to use a screwdriver and was not allowed to have the
wire cutters.

But anyway... I went on to get a BSEE and found that my abstraction of
electricity is somewhat akin to the paranormal. I won't bother
explaining that.
We are all familiar with combinations of things controlling something
else without really understanding why. For instance, if I pick up
something somewhat heavy and walk off with it, how heavy it feels has
more to do with how far I carry it and the grade it has to go up more
than how much the thing weighs. The distance and the grade control how
far I am going to carry the thing.
As distillers we are familiar with the combination of alcohol and
water. The amount of heat you apply to a boiler doesn't control the
boiling temperature it is the ratio of water to alcohol that
determines the boiling temperature(assuming something close to one
atmosphere).
With electricity it is the same way. The two fixed things are usually
the voltage and the resistance. These are the controllers. Current or
amperage is the controlled part. This is one of the most misunderstood
concepts in electricity. In order to change the current, you can only
change one of the other two. That is why I generally only refer to
wattage in terms of resistance and voltage, because the current is
going to do what the current does, completely dependent on the
resistance and the voltage.
