    Well, we usually assume that the resistance of a circuit component

    is constant and doesn't change. But the truth is that for anything

    that conducts current, its resistance always increases somewhat

    when it warms up.

    For things like light bulbs, electric toasters, space heaters, electric

    stove burners, the heat coils in a blow-dryer ... anything that's

    designed to be really hot when it's doing its job ... the resistance

    of those things increases significantly when they come up to their

    operating temperatures.
