What else can I help you with?
What heats the filament?
The electric current passing through the filament in an incandescent light bulb heats it up. This causes the filament to glow and produce visible light.
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.
How does the filament inside a light bulb produce light when electricity passes through it?
When electricity passes through the filament inside a light bulb, it heats up the filament to a very high temperature. This causes the filament to glow and emit light, a process known as incandescence.
What does a light bulb radiate?
A light bulb radiates visible light when an electric current passes through its filament, causing it to glow and produce light.
What transformation did electrical energy undergo to make the bulb glow?
The electrical energy was transformed into light and heat energy in the light bulb, causing it to glow. This transformation occurs when the electricity passes through the filament in the bulb, producing light and heat as a result of the filament's resistance to the flow of electricity.
Will the bulb light if the filament is broken Why?
No, the bulb will not light if the filament is broken because the filament is the part of the bulb that creates light when electricity passes through it. Without a functioning filament, there is no source of light in the bulb.
Is resistance in the filament of a lamp essential or not?
Yes, the resistance of the filament of a light bulb is what generates enough heat to make the filament glow and produce light.
How does a battery make a light bulb glow?
The flow of electrons from the battery flow through the filament in the bulb causing it to get hot and glow thus producing light.
Why does a fused bulb not glow?
A fused bulb does not glow because the filament of a fused bulb is broken. Since current can't flow through the filament, it can't get hot enough to glow.
You are using a bulb whose filament is broken will the bulb glow when connected to battery give reason?
No, the bulb will not glow when connected to a battery if the filament is broken. The filament is the part of the bulb that heats up and produces light when electricity passes through it. If the filament is broken, there is no path for the electricity to flow through and generate light.

Why is gas in a light bulb?
Mainly to prevent the filament, the glow wire from burning up.
Does the filament of an incandescent light bulb glow because it gets extremely hot?
yes
