All wire, including the wire in your house, has some amount of inherent resistance. And that resistance does cause some voltage drop proportional to the current flowing thru it. Done correctly, wire is sized so that the resistance (and therefore the voltage drop) is minimal for the amount of current that particular wire is expected to carry. The larger the wire the less the resistance and the less voltage drop for a defined current over the length of that wire.
