The light bulb stopped working because the filament broke.

In the early twentieth century, engineers experimented with various materials before discovering that a tungsten filament could withstand the high temperatures required for prolonged illumination.
Borrowed from Medieval Latin fīlāmentum, from Late Latin fīlō (“to spin, draw out in a long line”), from Latin fīlum (“thread”).
Commonly used in technical contexts like electronics, 3D printing, and biology.
