Hi mgb_phys, Thks. Yes, I understand the effect of electric field working at (near?) the speed of light. I relooked at some of the usual textbook explanation, which defines current as the rate at which charges flow, or I = Q/t. So if I put these thoughts together: 1. It is still true...

If not "electrons moving", what is the proper explanation? Hi mgb_phys, You said "electrons moving" is a wrong concept for understanding electric current. Could you help suggest a better way to explain this concept? I'm fully aware that "water pipe", "Bicycle chain", "electrons flow" have...

Hi, I'm trying to understand this concept in order to explain it to a child. Let's say I have a battery with a copper wire attached to each end of the battery terminals. No bulbs, no resistors, etc in circuit - just a wire. The battery creates an EMF that moves the electrons in the copper...
