Which is more powerful a torch bulb or a mains filament bulb?
Mains filament
What type of light is a light bulb that uses a filament?
A light bulb that uses a filament is also known as an incandescent light bulb.
Which has the thickest filament - a high-resistance or a low-resistance bulb?
A low resistance bulb has a thicker filament.
What is a light bulb filament?
the filament is the metal peice in a bulb that glows.Tungsten is most often used in a lightbulb.
What is light bulb filament?
It is the extremely thin wire inside the bulb. It is so thin that when the electricity goes through produce light, when that filament breaks the bulb is not good.
Is line spectrum obtained from filament of bulb?
filament of bulb
Which is more powerful a torch bulb or a mains filament bulb?
Mains filament
What is filament in a bulb?
The filament is the small coil that glows when the bulb is on. I believe its made out of tungsten
What is filament shaped into?
Bulb's filament are wounded into a coil.
Which is more powerful a torch bulb or a mains filament lamp?
Mains filament
When the bulb is the resistance what this tells about the resistance?
An incandescent bulb has a filament that has a resistance. The value of the resistance determines the current that will flow for a given supply voltage. The heat generated by the current flowing through the filament gives off light. As the resistance of the filament decreases the current increases and you get more light.
What type of light is a light bulb that uses a filament?

Which has the thickest filament - a high-resistance or a low-resistance bulb?
A low resistance bulb has a thicker filament.
Why are filaments of bulb coiled?
They have to be coiled in order for them to be long enough to produce enough heat, which produces the light in a small space. Otherwise the light bulb would have to be much larger.A filament bulb is coiled to allow a much longer filament to fit into a tiny space. It also reduces the amount of gas which flows across the inner portion of the filament.
What is the wire inside a light bulb called?
filament
