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


Sagot :

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.
