Why filament gets heated?
Filament gets heated when an electric current passes through it, causing resistance in the filament wire. The resistance converts electrical energy into heat energy, which then causes the filament to reach high temperatures and emit light.
What is the main type of energy transformation that occurs in the filament of a light bulb?
Electrical energy (the electric current) is transformed into thermal energy (by heating the filament to incandescence), and this thermal energy creates electromagnetic energy in the form of light.
Why does the current loose some of the energy when it passes through a bulb?
When current passes through a bulb, it encounters resistance in the filament of the bulb. This resistance causes some of the electrical energy to be converted into heat and light, resulting in a loss of energy in the form of heat radiation.
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 kind of energy does a light bulb give out?
A light bulb gives out light energy when electricity passes through its filament, causing it to glow and emit light. Additionally, some energy is also given off in the form of heat due to the resistance in the filament.
Does energy change when it passes through a light bulb filament?
The energy won't change

What happens to the electrical energy carried by the current when it passes through the filament of a bulb?
it stays there. the electricity travels back and forth through the filament until you turn the lighbulb off.
What happen to an electric current after it passes through each bulb?
There is a piece of filament in every light bulb, which has so much friction that when the electric current passes through it, heat energy is produced. This heat energy is then converted to light energy.
Does a flashlight form electricity?
No it does not FORM it. It converts chemical energy in the battery cell into electrical energy which is then passed through a thin wire called the filament at the bulb. The filament lights up when electricity passes through it, thus giving out light.

Why does a bulb glow when electric passes through it?
The filament in the bulb has resistance. The current flowing through the resistance of bulb causes the filament to dissipate energy in the form of heat and light. The filament is actually glowing white-hot because of the energy it is dissipating, thus giving off light.
What kind of energy does a light bulb give out?
A light bulb gives out light energy when electricity passes through its filament, causing it to glow and emit light. Additionally, some energy is also given off in the form of heat due to the resistance in the filament.
What is the energy transformation in the torch?
In a torch, electrical energy from the batteries is converted into light energy through a process called incandescence. The electric current passes through a filament, heating it to a high temperature and causing it to emit light.
What is the energy conversion of lamp?
A lamp converts electrical energy into light energy through a process called incandescence or fluorescence. The electrical current passes through a filament or gas-filled tube, causing it to emit light.
