In which direction does direct current flow?

Question

Electronics

Charge carriers in metals are electrons that move from the negative pole of the source to the positive, but the direction of the current is considered to be (as they say in many sources - "conditionally") the movement of charged particles from "+" to "-". The figure shows a simple circuit that, for educational purposes, is designed to demonstrate how resistance affects the rate of charge accumulation on a capacitor.
If there were no ready-made circuit, but it became necessary to assemble something like this, how can one guess, based on the above, that the resistance should be located where it is, and not between the capacitor and the "-" of the current source? I would like to get a more detailed explanation about the movement of current.

Thank you.

Answer 1

With the same success, the resistance can be between the capacitor and the "-" of the current source. It has nothing to do with the direction of the current.
