And engineering is just the application of science. We just get to call things "close enough for practical purposes" and skip some of the nastier math, which is why EE's use Voltage to begin with (as opposed to working EM-fields for everything).
The bigger question is what an electron, and an electric field, really is.
We know it's a subatomic particle. We now we like to think of it as "negative". And we now we like to build little highways for our electrons, called circuits, and by letting them whizz around there we can do all kinds of fancy stuff like heat up wires (lightbulb, owen) or induce magnetic fields to move things around (speakers, motors).
But is it really "negative". Positive and negative are just words which we've attached to a phenomena to make it easier to think about it. But what is an electron really? And why should that little bastard over there be attracted to some other little thing there, called a proton, which we like to think of as "positive"?
Riddle me this... riddle me that....
Like with so many things in science we don't know the why, but we observe and create our little theorems thinking that we've understood something.
And every once in a while some human comes along and builds an amplifier and listens to barbie girl, but hey such is life.
(I think I should call it a night already, I've clearly had enough of my trippy pills)
The real trick about science is whether or not it is useful. Specifically, whether or not we can make predictions. I think science and engineering has given you a hobby that you love, and you ought to respect it
