Resistance also depends on the material of the conductor. See resistivity. The resistance of a conductor, or circuit element, generally increases with increasing temperature. When cooled to extremely low temperatures, some conductors have zero resistance.
What causes resistance to increase?
As electrons move through a metal conductor, some collide with atoms, other electrons or impurities. ... Heating the metal conductor causes atoms to vibrate more, which in turn makes it more difficult for the electrons to flow, increasing resistance.
How do you increase resistance in a circuit?
length - longer wires have greater resistance. thickness - smaller diameter wires have greater resistance. temperature - heating a wire increases its resistance.
