    i need help-
    How does the temp + length of a wire change its resistance?
    AHA

    increase temp => increase resistance
    increase length => greater resistance

    increase temp => increase resistance
    if its a metal wire. if it is a semiconductor wire, increased temperature will decrease resistance.

    i think were supposed to assume wires are made out of metal. I've never heard of a wire being made out of a semi conductor material.
