I turned on the toilet light that day and the bulb suddenly exploded, why

It may be due to the excessive force and urgency when pressing (pulling) the switch, causing the starting current to be too much and the filament will burn instantly, and the high temperature will be generated in the bulb, and then the outside of the bulb will be humid, and it will break and explode due to uneven heating.

The bulb generates high temperature, and at this time, the bulb is damp outside, and it bursts due to uneven heating, and the explosive current is too much, and the filament burns instantly.

It may not be possible to know.

But the bulb exploded, I guess it may be that the air intake in the bulb is no longer vacuum, so the incandescent bulb filament is instantly overheated and burned, and after studying high school physics, we know that the current I is the largest at the moment when the electrical appliance is started, and the cold air blows up the glass outside.

It could be that your bulb itself already has a crack.

The moment you turn on the light bulb.

The bulb is subjected to too much current.

When the air enters, it explodes.

When the current is excessive, the filament burns instantly, and the high temperature inside the bulb is generated, and then the outside of the bulb is damp, and it bursts and explodes due to uneven heating.

It could be that your light bulb itself has cracks and is dying.

Because so.

Scientific truth. I'm in my first year of junior high school.

Only sparse and shallow.

After studying high school physics, we know that the current I is the largest at the moment when the electrical appliance is started, so the incandescent bulb filament instantly overheats and burns short.

But the bulb exploded, and I guess it may be that the air intake in the bulb is no longer vacuum, and the cold air is hot and blows up the glass outside, so I don't know if it may be impossible.

The brothers upstairs have already gone into great detail, so I don't need to say more. Earn a point and leave

Because of this, scientific principles, astronomy and geography, your mother is reasonable, last night, walking on the road, was insulted, ask yourself!
