... Answer: The 40W bulb is brightest! When a bulb is marked "40W", it means: IF the bulb is connected to 120VAC, it will put out 40W power. In the series circuit, none of the bulbs is connected to 120VAC, so the labels are not correct indicators of power/brightness. This problem requires multi-step rea ...
