How does a Light Bulb work? | Mocomi Kids

mocomi.com/ presents: How do light bulbs work? An informative video about the working of a light bulb. Check this out and find out for yourself! A light bulb is a simple apparatus that converts electric energy into light energy. The law of conservation of energy says that energy can neither be created nor destroyed, it simply changes form. A light bulb is able to take the the electricity supplied to it and change its form into something that can be used for illumination. A bulb is made up of a positive and a negative terminal embedded inside glass with a tungsten filament that joins the two. When electricity is supplied to the terminals, the flow of electrons heats up the thin filament in between. The electrons continue to bang against the filament until it heats up to the point that it begins to glow. This process happens extremely quickly. The filament is encased inside transparent glass to let the light shine through and also to protect it from overheating. The air inside the glass is actually a small amount of inert gas that helps prevent the filament from becoming too hot and breaking. When the light bulb has fused it means that the thin coil inside has snapped and therefore electricity cannot flow completely through the circuit. #LightBulbWork #Light #Science For more information about working of light bulbs, read: mocomi.com/how-does-a-light-bulb-work/ Watch more science videos in one go here    • What is a Pulley? - Simple Machines |...   Subscribe here for new and interesting content every week ► ► youtube.com/mocomikids?sub_confirmation=1 Press Bell Icon 🔔; For Latest Updates.
