What parts of a light bulb are conductors or insulators?

Answer 1

The conductors are the two wires you see supporting the filament. The glass supporting all this is an insulator. The metal ring around the base and the very bottom of the bulb conduct the electricity into the bulb. The plastic between them is an insulator.

In incandescent bulbs, the filament of the bulb is a conductor, but has a high resistance to the flow of current, causing it to heat up and glow.

In fluorescent bulbs, the gas in the tube resists the flow and is ionized. The ultraviolet photons that it gives off cause the inside of the tube (coated with phosphors) to glow.

Answer 2

Light bulb is itsef composed of many parts like filament wire and external casing of glass. Among which current flowes through the tugasten filament wire which is a 'conductor' of high resistance.

Answer 3

The light bulb has an insulator between the conductor that leads up to the filament and a conductor that leads away from the filament. The atoms of conductors accept and pass on the electrons the atoms of insulators don't.

Answer 4

The filament inside a light bulb is a conductor as it allows electricity to flow through and generate light. The glass casing of the light bulb acts as an insulator to protect against electric shock and to contain the electrical components.

Answer 5

Conductor, otherwise it wouldn't light up. The current flows through it, but it has a resistance to the flow (it is a resistor) and releases some energy as heat and light.

Answer 6

Bulb filaments are high resistance conductors. They must be conductors to let the electric current thru but they must also offer enough resistance so the filiment gets hot enough to glow.

Answer 7

In a light bulb the conductor is the the metal filament inside which gives off the light and also, the metal base of the lightbulb is a conductor.

Answer 8

Yes, the bulb must conduct the electricity to complete the electrical circuit. The bulb, however, is also going to absorb (use) the energy once it begins to flow.

Answer 9

The light bulb itself is not a conductor but the filament inside the bulb is.

Answer 10

It has high resistance.
