Incandescent light bulbs might not be the new kid on the lighting block anymore, but the science behind them is as fascinating as ever.
Traditional incandescent light bulbs operate under a pretty simple principle. When electricity is forced through a thin and resistant metal that metal produces heat–light is simple a very welcome by product of the process. In the above video Bill Hammond of EngineerGuyVideo delves into the science of light bulbs and why Tungsten, an unassuming and not particularly ductile metal, is the magic ingredient.
