Inside a Fluorescent Lamp

The central element in a fluorescent lamp is a sealed glass tube. The tube contains a small bit of mercuryand an inert gas, typically argon, kept under very low pressure. The tube also contains a phosphor powder, coated along the inside of the glass. The tube has twoelectrodes, one at each end, which are wired to an electrical circuit. The electrical circuit, which we'll examine later, is hooked up to an alternating current (AC) supply.  See diagram below.
