Why do the current arrows point the wrong way?
If you’re studying for your amateur radio licence, but happen to know a little basic Physics, you may be confused by some of the training diagrams depicting current flow.
In the diagrams, you’ll see the direction of arrows showing current flowing from positive-to-negative, but in practice, electrons actually travel negative-to-positive.
Despite this, it’s common to show positive-to-negative, as that’s how it’s been written for years, and way before the behaviour of electrons was understood. It’s referred to as Conventional Current Flow
