Anonymous users2024-01-24There is no need to replace all the bulbs in the living room that suddenly burst when they are turned on, and the temperature that the bulb needs to withstand is 8000 degrees. When the light is turned on, the instantaneous temperature of tungsten wire is generally about 7000 degrees, and sometimes it may reach more than 8000 degrees. That's because the voltage is too high at the moment you turn it on.
But it's a burst. It's not an explosion, it's generally impossible for a light bulb to explode, and it's only seen in a movie, so you can rest assured, there's no need to change all the light bulbs

I have done a similar experiment, that is, after the filament length is shortened, the temperature of the filament suddenly increases, and the bulb shell cannot withstand it and bursts, which is the bulb explosion.

It's possible that it tripped. You go to the main switch, hit it down and put it back on.
It should be that the contact at the lamp port of the lamp is poor, or the contact is corroded, resulting in the increase of the resistance of the contact, and the power is local overheating, which makes the bulb break, or the contact between the bulb and the bus is problematic, resulting in a situation similar to a short circuit, so that the instantaneous current increases, and the main switch jumps open. It is recommended not to use bath bombs, especially PVC ceiling materials, which can easily lead to PVC softening and deformation when used for a long time, and even reports of fires. If you have children, don't use bath bombs, as the bright light will stab your children's eyes.
Oh? UMC too.
Generally, the circuit settings of the family are in parallel, and if one is bad, the others can still be used. >>>More
It may be that the light bulb will break after a long time, and the lights in our school are often like this, and it will be fine if you change the bulb, and it will be fine, but it is best to find someone with a little knowledge of physics to get it, and don't get electrocuted.
The water pipe burst suddenly, the kitchen pots and pans are filled with water, you don't believe in feudal superstitions, this may be because the water when the pipe bursts is just filled with pots and pans, and your son is born has no big relationship, there is no good or bad.
