Ashort, thick, cold wire is the best conductor. a shorter wire will allow electricity to move through at a higher rate than a longer wire. how well a material conducts current is an internal factor affecting resistance. if you double the length of a wire, you cut the resistance in half. if you double the thickness of a wire, you cut the resistance in half. superconductors have no measurable resistance. the higher the temperature of the conductor, the lower the resistance. the resistance in a wire with less thickness is less. thickness, length, and temperature are internal factors that affect resistance. when a light is first switched on, the light bulb's filament has a lower resistance than after it gives off light for awhile. true false
