My simple understanding is in a dc circuit current flows out the positive terminal of charge source and back to the negative terminal of the same charge source.
If... the voltage is sufficient to overcome the resistance along the path.
If the path is air the resistance if relatively high.
If the path is copper the resistance is relatively low.
Is it conceptually valid to imagine the charge source sucking up electrons on the negative terminal?
Like negative pressure?
