TPR- physics- Direction of current/Electric field flow

I am a little confused on the concept. This is what it says in TPR book, "The conduction electrons will drift from neg terminal to positive terminal . The direction of the flow would be clockwise. The direction of the current is taken to be the direction that positive charge carries would flow, even if the actual charge carriers that do flow aren't positive. Even though we know electrons are drifting clockwise, we'd say that the current flows counterclockwise, from the positive around to the negative terminal"

and how does relate to, electric field vecotrs always point away from positive sources charges and negatives ones?

Thanks for any help, physics is really kicking my butt.. Any tips on how to get through physics? I am getting so overwhelmed.. =(

It's just a (dumb) physics convention. If electrons are leaving an area, then positive charge must be entering it by virtue of the fact that there's the same amount of positive charge as there was but less negative charge.

is that all they were trying to say? The clockwise and counterclockwise confused me. And how does this tie into the concept of electric field vectors always point away from positive sources charges and negatives ones?

man, it has been years since physics so its like learning everything over again.. sigh... Thank you so much for the help. 👍
