Understanding Conventional Current: Is It Directed Back into Source?

[LanguageNerd]

I understand, thanks to basic physics concepts, that when the electrons flow through the circuit from the negative terminal to the positive terminal, the conventional flows from the positive terminal to the negative.

Am I right in thinking that in firing an electron beam, the conventional current produced is actually directed back into the source producing it?

May be quite simple but it's quite difficult to try and imagine.

Thanks for all help in advance,

I too had the confusion but consider it as taking and giving charges. Let us consider a 5 C charge system. Take 1 C to it, you get 4 C. Give -1 C to it, you get same 4 C charge system. This is a simple argument to show that the direction of current (positive charge) is opposite to the flow of electrons.

This is correct. For example, if you put a coil of wire and let these electrons pass through the center, then the induced current in the coil is in the same direction as if you have positive charges going the opposite direction.
