I learned in elementary school not to trust books or teachers because they both said "electricity never flows through an open circuit". Since my shoe bottoms were rubber, I was an open circuit when I stuck a paperclip in 1 hole in the outlet in class and got shocked.

Teacher tried to talk me out of it before I did it, but the only way I would accept is if she said electricity sometimes flows through an open circuit. She wouldnt, defended the book like it was holy, but said "its complicated", but complication cant change something that never or always happens so I cut that off with occams razor. It does flow through an open circuit, just enough to feel it strongly. AC is just DC that changes direction, so DC laws of physics still apply. Dont allow any statement in physics books thats sometimes false, planning to "update" it later when students know more. Leave things unknown until they become known, not sometimes wrong until they become known. Cuz someone might believe it. I acted correctly, and it was that teacher's and book's fault.
