hi! Can anyone explain how an electric field propagates from one point to another? For example if i touch two 6ft wires to the ends of a 5V battery, i'll get 5V across the end of the wires after a propagation delay. How does the electric field (voltage) of the battery make it's way down to the ends? also, if my understand is correct, there are no additional electrons being added, so are the electrons just under a greater force now? If electric field is a measure of distance, do i get a different potential if i hold the wires 1 ft apart as opposed to 3ft apart? Thanks!
