What is an electrical insulator and conductor?

Is a light bulb a conductor yes or no? A 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.
Does a light bulb have an insulator? Today, we continue to add to the list of inventions that depend on electricity. Electricity flows along a path called a circuit. To create a circuit, you need a battery, wire, and a bulb.
