Problem 13CQ

Why do incandescent lightbulbs grow dim late in their lives, particularly just before their filaments break?

Step-by-Step Solution:
Step 1 of 3

Solution 13CQ

 The resistance of the filament increases as the bulb ages due to repeated heating and cooling and reduction in the thickness of the filament.

So, with the applied voltage staying the same, the current flow through the filament decreases and the bulb glows less bright when it gets old.
