Two 110-V light bulbs, one â25Wâ and the other â100Wâ, areconnected in series to a 110V
source. Then:
A. the current in the 100-W bulb is greater than that in the 25-Wbulb
B. the current in the 100-W bulb is less than that in the 25-Wbulb
C. both bulbs will light with equal brightness
D. each bulb will have
E. none of the above

Two light bulbs use 30 W and 60 W, respectively, when connected in parallel to a 120-V source.

How much power does each bulb use when connected in series across the 120-V source, assuming that their resistances remain the same?
