Fused bulb
the filament is the metal peice in a bulb that glows.Tungsten is most often used in a lightbulb.
The resistance of the filament in a light bulb is(voltage at which the bulb is designed to operate)2/(the rated power/watts of the bulb)
a fuse bulb is a bulb in which the filament of the bulb burns and it stops working
