What happens to the energy when you turn on an electric lamp?
Electricity flows through the filament, resistance in the filament causes heat and light energy to be created.
What happens during a light bulb burning out?
A light bulb works by passing electricity through a long, thin piece of metal that is called a filament. The electricity heats up the filament much like an electric stove heats up its elements. The heat, through black body radiation, causes the filament to emit light. But, the heat also stretches and thus weakens the filament. Over time the weakening will break the filament along the heated portion and this is called "burning out" in common language.
Why does the light bulb not work when the filament is broken?
A light bulb works by passing an electric current through the filament, which is usually made from a high resistance substance such as tungsten. When the current flows through, the filament glows which produces the light. When it burns out, no electricity passes and no glowing occurs. Source: i just know
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 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.
What happens to the filament when light bulbs blows?
The filament breaks.
What happens to the energy when you turn on an electric lamp?
Electricity flows through the filament, resistance in the filament causes heat and light energy to be created.
When electricity pass through the bulb what happens to the filament?
It gets heated up and glows spreading the light
Why do light bulbs have the coil in the middle?
That is the filament. Electricity traveling through the filament heats it to the point of glowing brightly - that is the light bulbs "light".

What is an incandascent lamp?
Your standard light bulb where a filament is heated by a current passing through it. The heated filament then gives off light.
Is a light bulb a soure of light?
Yes, a light bulb is a source of light. When current is going through the filament the resistance generates enough heat that the filament glows, producing light.
What is electrical energy converted into when electric current flows through the metal filament of a light bulb?
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
Property of the filament that makes it light up when electricity flows through it?
Incandescence. The filament is heated by the electricity moving through it, this causes the filament to heat up, and the heat causes the familiar glow.
What is the filament in lights?
Filament is a thin part of incandescent bulb which is the source of electric light that electric current passes through and heated it until it produce light.

How do tungsten-halogen bulbs generate light?
Inside a tungsten-halogen bulb, electrons flow through a tungsten filament. The filament heats up and emits light.
