What happens when a lightbulbmlc-co5)) nal7,o*h-j p cw vgst5-c88iejctp58 qw bda06j o burns out?
参考答案:
When
a light bulb burns out, its filament burns in two. Since the filament is part of the conducting
path for the electricity flowing through the bulb, once the filament is broken,
current can no longer flow through the bulb, and so it no longer gives off any
light.
