What is the purpose of the filament in a light bulb with filament?
The purpose of the filament in a light bulb is to produce light when electricity passes through it, causing it to heat up and emit light.
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.
Can a bulb light if electricity doesn't get to the bulb?
No, a light bulb will not light up if electricity does not reach it. Electricity is required to flow through the filament in the bulb to generate light. If there is no electrical current, the bulb will not illuminate.
Why do you need electricity to light a light bulb?
Electricity is needed to light a light bulb because the flow of electrons through the filament inside the bulb generates heat and light energy. This energy causes the filament to emit light, thus illuminating the bulb. Without electricity, there is no source of energy to power the light bulb.
What happens when electricity flows through the filament in a light bulb?
When electricity flows through the filament in a light bulb, the filament becomes very hot and starts to emit light due to the process of incandescence. The electricity heats up the filament to a high temperature, causing it to glow and produce light.
What provides the energy to light a light bulb?
Electricity provides the energy to light a light bulb. When the electricity flows through the filament in the bulb, it generates 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 is the source of energy in a light bulb?
Electricity is the source of energy in a light bulb.
Where does the electricity go in a light bulb?
Electricity flows through the filament of a light bulb, heating it up and causing it to emit light. The electricity powers the light bulb, allowing it to produce illumination.
What is the filament inside a light bulb?
The filament inside a light bulb is typically made of tungsten. When electricity passes through the filament, it heats up and produces light through incandescence.
What happens if the filament breaks?
If the filament in a light bulb breaks, the circuit is interrupted and the light bulb will no longer illuminate. This is because the broken filament is unable to produce light when electricity flows through it.
What do the wires in the middle of a light bulb do?
The filament is made of tungten and these 'wires' (filament) conduct electricity.
