I've always wondered about the design choice for the shape of batteries. It seems like the shape would indicate the current is flowing the opposite way than it does. Something about the positive terminal just says to me "I'm shooting electrons this way"
- digi_owl 11y agoI got the impression from somewhere that plus and minus was defined long before they could track actual electrons, and thus discover that they had them backwards.
- lr4444lr 11y agoIt's an historical accident. But electricity as the flow of positive charge is a pretty reliable model outside of materials science and nano-electronics, so why worry?
- delinka 11y agoSomething that bugged me as a kid trying to learn electronics: everything is connected to ground, negative is on ground, so we're dumping electrons onto every path in the circuit. It's the job of the resistor, capacitor, transistor, IC, etc, to direct those electrons, putting their energy to use, and then dumping them back to positive.
