N Europe the standard voltage in homes is 220 V instead of the 120 V used in the United States. Therefore "100-W" European bulb would be intended for use with a 220-V potential difference.

(a) If you bring a "100-W" European bulb home to the untied States, what should be its US power rating?

(b) How much current will the 100-W European bulb draw in normal use in the United States?
