Superconductors are materials that have very low or no resistance to the flow of electricity. These materials usually need to be very cold for this property to appear.

Why isn't there voltage drop in a 240 volt system?

Regarding the question of "Why isn't there voltage drop in a 240 volt system?" The smart alex answer is "because no current is flowing." Only if no current is flowing can there be no voltage drop in any circuit. All conductors, even supercondutors, have resistance and this resistance will produce a voltage drop when a current is flowing through the conductor(s). 240 volts is used over 120 (or 12 volts) because it reduces the current reguired for a fixed amount of POWER (watts). Therefore, the conductor size can then be reduced to reduce cost, size, weight or to improve flexibilty.
