I know that in AC, the direction of the flow of electrons is constantly changing, but this question is for a DC circuit like an LED with a battery.
Does current in such a circuit flow from the - side of a battery to the + side of a battery? This makes sense to me as the negative side wants to get rid of the negative electrons as it has too many, and the positive side wants to gain electrons so they move in that direction.
But recently I've heard that it's actually the other way round? + > - I've also heard this is to do with how electricity was first discovered and they got it wrong? Now I'm really confused on which way it actually flows, or if it's just the naming of the positive and negative sides of a battery are inverted..
Could somebody shed some light on this? I would appreciate it very much.
