Actually, electricity is so easy to understand that mathematicians are thrilled when they get to use electricity as a metaphor to gain insights into more abstract systems. The poster child for this approach would be the spectacular book:

Probability on Trees and Networks by Russell Lyons and Yuval Peres https://rdlyons.pages.iu.edu/prbtree/

As a comment on the style of "Why is electricity so hard to understand?", mathematicians get inundated with crank missives claiming simpler proofs of Fermat's Last Theorem, and many other hard problems. On one hand we try not to judge the delusion, as it takes a certain amount of delusion for any of us to find the confidence to overturn old ideas. Yet there's a balance here. With cell phones, the ability to self-rescue in the woods has gotten lost. Even the most delusional serious mathematician knows how to "self-rescue". Part of commanding one's work is understanding it in context, and to see how one might critique it, more incisively than any potential reader. This is not unique to math; "writer's block" is a writer losing control of this balance, just as insanity is anyone losing control of their inner chaos.

"Why is electricity so hard to understand?" is indulgent; it doesn't even try not to read like a crank missive.

I often reply to crank missives with advice on how not to be immediately coded as such. The world would be more fun if we were unable to tell the crazies apart from everyone else. Alas this advice rarely takes.
