   * The electron current going into a location must be the same as the current leaving that location because [[184_notes:charge|charge is conserved]].   * The electron current going into a location must be the same as the current leaving that location because [[184_notes:charge|charge is conserved]].
   * The electron current moves through the wire because there is a constant electric field inside the wire. This electric field comes primarily from the [[184_notes:q_in_wires|surface charges along the wire]].   * The electron current moves through the wire because there is a constant electric field inside the wire.
