As a layperson, electricity is one of those things that seems really complex and dangerous to mess with. But we've managed to abstract it down to "plug this cable into a socket" or "flip a switch". I remember doing the V = IR calculations in highschool, the difference between alternating and direct currents, as well as the relationship between volts and amperes.

While fascinating, none of that translated to real world working knowledge. In fact I was greatly surprised to learn about how my outlets are actually wired when I had to get my home's electrical panel replaced. Turns out, swapping electrical outlets and switches is actually really easy, but I only felt confidence once I had an electrician show me. Otherwise I would still be too worried about burning my house down
