WebA light bulb is a relatively simple device consisting of a filament resting upon or somehow attached to two wires. The wires and the filament are conducting materials that allow charge to flow through them. One wire is connected to the ribbed sides of the light bulbs. The other wire is connected to the bottom base of the light bulb. Webing of the basic electrical and optical chara- c teristics of the lightbulb is an appropriate sub-ject for study in the introductory physics class. The first incandescent lamps consisted of a filament of carbon wire in an evacuated glass bulb, two ends of the wire being brought out through a sealed cap and then to the electric supply.
