Explanation:
In Europe the standard voltage in homes is 220 V instead of the 120 V used in the United States.
100-W European bulb would be intended for use with a 220-V potential difference.
(a) If V = 220 V and P = 100 W
Power :
If you bring a "100-W" European bulb home to the untied States, what should be its US power rating. So,
or
P = 29.8 watts
(b) Let I is the current will the 100-W European bulb draw in normal use in the United States. So,
Hence, this is the required solution.
