Can anyone tell me which ones of these are true and which ones are false pls
a shorter wire will allow electricity to move through at a higher rate than a longer wire.
a short, thick, cold wire is the best conductor.
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.
