I am curious about what would happen to an electrical current in 2
situations.....

Assume that you have 2 wires that, when joined, complete a closed

electrical
DC circuit with electrons flowing thusly.....

If you flattened out the end of each wire where they connect , would the
resulting electron paths be more like figure A or Figure B?


neither ... research "skin effect"


Figure A

Figure B

eeeeeeeeeee eeeeeeeeeeeeeeeee

(Please note that the vast # of "e"lectrons shown in Figure B is simply to
show the path's of electrons. )

The second portion of my question is....If the flattened portions were
increases in mass (if each wire were connected to a metal cube and the

cubes
were brought together to complete the circuit) how would it effect

electron
flow where the cubes touch?


electron flow (or hole flow is you prefer to think that way) is determined
by total circuit resistance. (and applied EMF as per ohms law) decreasing
total resistance by increasing contact point surface area will result in
increased current flow if all other factors remain the same.



Thanks for your help.
