When voltage is applied across a wire, a current flows 
Imagine *e-'s go up V stairs* - ANSWER-*Electrons* move from *lower to higher voltage* (opposite to current "+ charge") 
The current makes electrons flow into the wire and out of the wire (equalling each other), so the net charge on a wire will not change. 
The *net charge i...
