A light bulb provides light to a room or place or street. It does this by two filaments powering up together and making an electrical charge which makes a spark and turns on the light. Search what does a light bulb do? On google if this doesnt answer your question. By Katy.

It provides you with a better way to see instead of a candle. They have to have energy to work.
