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.
