What else can I help you with?
Is a light bulb an insulator or conductor?
It is a conductor, but the filament is a resistor : as current flows through the filament, some of the energy is released as heat and light.
Why is a filiament lamp a non ohmic conductor?
A filament lamp is a non-ohmic conductor because its resistance changes with applied voltage. As the voltage increases, the resistance also increases. This is due to the temperature-dependent behavior of the filament material, which causes the resistance to vary.
What filiament did Edison use in the first successful light bulb?
Edison used a carbonized bamboo filament in the first successful incandescent light bulb he created. This innovation allowed the light bulb to produce light for longer periods of time without burning out.
Why is tungsten suitable for making filament of a bulb?
Tungsten is suitable for making a filament in a light bulb because it has a very high melting point, allowing it to operate at high temperatures without melting. It also has a low vapor pressure at high temperatures, which helps the filament last longer without evaporating. Additionally, tungsten is a good conductor of electricity, making it efficient at converting electrical energy into light.
Is it poor conductor or a good conductor?
It is a poor conductor.
Is a light bulb an insulator or conductor?

What should be the conductor of the curcuit so the filament doesn't melt?
Tungsten
Is a light a conductor or a insulator?
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.

What elements are in light bulbs as a filament?
Light bulb filaments are usually made of tungsten, which has a very high melting point. Occasionally carbon is used as a filament.
The part of a light bulb that is a poor conductor so that the friction causes it to light up and glow?
The filament inside a light bulb is typically made of tungsten, which is a poor conductor of electricity. When electricity flows through the filament, it encounters resistance, which causes the filament to heat up and emit light.
Why is a filiament lamp a non ohmic conductor?
A filament lamp is a non-ohmic conductor because its resistance changes with applied voltage. As the voltage increases, the resistance also increases. This is due to the temperature-dependent behavior of the filament material, which causes the resistance to vary.
What is a filament resistor?
A filament bulb resistor is the common type of light bulb. It contain a thin coil wire called filament. It produces light as a result. It is made mainly from the element tungsten. The metle tungsten has very high melting point and it is a good conductor of electric current
What is the filament purpose?
If you are asking about a light bulb, the threadlike conductor, often of tungsten, that is heated to incandescence by the passage of current
