There are two issues that affect the maximum length of a wire that can be used. The first is the gauge of the wire and the second is the current that is being used. If the resistance of a length of wire is 100 ohms and the current that is going down the wire is 1 amp then V=IR, so the voltage drop on the wire is 100 volts.
