Inrush current flow

So I recently watched a video on inrush current, the current flow that is initiated when , for instance, a lightbulb circuit is first turned on. On some bulbs it can 4 times the rated current of the bulb. Does it not pop a fuse because the overflow is so short?

The fuse doesn't blow because the high-current inrush doesn't last longer than a few milli-seconds. Light bulbs have a "Positive Temperature Coefficient". When the bulb is cold resistance is at its lowest, and current is at its highest. As soon as the bulb is energized, it heats up. Resistance increases and current decreases. This happens so fast that the fuse, for lack of better words, doesn't have time to blow.

Thanks man, I figured there was a logical answer out there. I did see how fast the bulb heats up. It was like half a second or less. So that all makes sense.

Was this the video from Rob Dotterer you watched?
