Just a quick question regarding this comment, are protons not bound to the atom structure i.e. they can't move around like electrons? I've heard of proton shuttling not sure if it applies here, and iam aware of holes in semiconductors.The electrons don't circulate inside the battery, only protons (depending on the battery).
Another question regarding electric fields, when this stuff is being described in a book there is dicussion about a charge and its electric field potential dropping of at 1/r, does one assume that they are always taking about a single electron charge or a group of charges or ions? Also the units for electric field potential is V/cm^2 and i find it confusing that something that is powered from say 6v can have electric field up to kV/cm^2 is this correct?
I was just passing through the forum so if the detail seems a bit sketchy i will try to provide an example later, or move my question into another topic.
