PLEASE HELP!!!!!!!!!! What is the difference of voltage form one end of a conductor to another? (Charge flows from higher potential to lower potential.)

The difference in voltage between the ends of ANY component in an electrical circuit is             (the current through it) times (its resistance) .That goes for a resistor, a heating coil, a light bulb, or a piece of wire.  Of course, the resistance of the wire is made as small as possible, so the difference of voltage between the two ends of a wire will also be very small.
