Resistance: temperature coefficient since the electrical resistance of a conductor such as a copper wire is dependent upon collisional proccesses within the wire, the resistance could be expected to increase with temperature since there will be more collisions, and that is borne out by experiment. A piece of thin wire has higher resistance than a piece of thicker wire with the same length, which means that it's harder for electric current to move through it if you use the same battery but replace a thick wire with a thinner one, the electric current will get smaller and a light bulb in the circuit should get dimmer.
