    What do you call "normal"?

    They have various ratings, some as low as 0.04W.

    Best to look at the datasheet to be certain.

    The entire resistive element has a max power rating of about 1/2W. If only half the element is in-circuit then its rating is only 1/4W. If only a small portion of the element is in-circuit then it might smoke and burn.
