How Electricity Makes Light: Science Explained!

Creator: A/V Geeks 16mm Films

Description: We explain how electricity produces light. Our filament, made of tungsten, resists the flow of electricity, heats up, and glows instantly, creating light. Learn the science behind instant illumination. #Electricity #LightBulb #ScienceExplained #Physics #HowItWorks #Tungsten #Filament #ElectricalEngineering #DIYScience #Education

Transcription

Now let us see how electricity makes light. Inside a lamp bulb is a very small wire called a filament. It is made of a kind of metal called tungsten. Electricity has trouble getting through this type of small wire. And as it does the wire becomes hot, glows and we have light. Of course it doesn't take this long when we turn on the light. The filament gets hot and we have light in an instant.
