Do you even know what "electricity" is? Most people don't, since the term is pretty meaningless. Or rather, has too many meanings - and those meanings conflict with one another.
Nope - probably part of why it holds no meaning for me - too broad a subject to grasp at a macro-level.
To narrow it down, I can implement all kinds of functionality using logic gates, but I just recently stopped turning off the breakers to change light bulbs. I enjoy reading about the physics of electromagnetism, but get nervous jump-starting vehicles.
So I suppose its the day-today, practical application of household electric that I don't really grok: AC vs DC, 220V, amps, breakers, junction boxes, grounded outlets, etc.
