Two light bulbs, one 60 W bulb (higher resistance) and one 100 W bulb (lower resistance) are placed in series. A current is run through them. Which bulb glows brighter?
A. 60 W bulb
B. 100 W bulb
C. Same
D. One bulb would not light
The answer is A. I'm not sure how to arrive at the answer. I thought the answer was B because I thought that power would be a measure of the brightness of a bulb. Apparently not. How would you reason that a 60 W bulb would be brighter in series with a 100 W bulb?
