The power rating on a light bulb indicates how much power it would dissipate when it is hooked up to the standard household voltage of 120 V (this rating does not mean that the light bulb always dissipates the same amount o power).
A) How much power is dissipated in a light bulb that is normally rated at 60W, i instead we hook it up to a potential difference of 100V?
B) How much power is dissipated in a light bulb that is normally rated at 60W, if instead we hook it up to a potential difference of 200V?
