It is when it is heated by electric power, when it gives off heat and light.

What form of energy is heat produced by filament?

The heat produced by a filament is primarily thermal energy. When an electric current flows through the filament, the resistance of the filament causes it to heat up, converting electrical energy into heat.


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.


What are the steps to trsnsfer energy when you turn on a light?

When you turn on a light, electrical energy from the power source is transferred through the wires to the light bulb. The electrical energy is then converted into light energy and heat energy by the filament in the bulb, illuminating the surroundings.


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.


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 are the energy transformations occurring in a filament lamp?

In a filament lamp, electrical energy is transformed into both light and heat energy. The electrical energy is converted to light energy as the filament heats up and emits light. However, a significant portion of the electrical energy is also converted to heat energy due to the resistance of the filament.


Why is a coiled filament better than a staright filament?

A coiled filament in a light bulb is more energy-efficient than a straight filament because it allows for a longer filament to fit in a smaller space, providing more surface area for light emission. This leads to increased brightness while using the same amount of energy compared to a straight filament.


What causes the bulb to light in a closed circuit?

In a closed circuit, electrical current flows from the power source through the wires, through the bulb, and back to the power source. When the current reaches the filament inside the bulb, it heats up and emits light, causing the bulb to light up.


What is the energy transfer in light bulb?

In a light bulb, electrical energy is converted into light energy and heat energy through the process of electrical resistance in the filament. The filament gets hot and emits light, leading to the transfer of energy from electrical form to light form. Some energy is also lost as heat due to resistance in the filament.


What causes electrical energy to be transformed into heat and light energy as a current flows in a light bulb?

As electric current flows through the filament of a light bulb, resistance in the filament causes electrons to collide with atoms, generating heat energy. This heat energy leads to the filament glowing and emitting visible light. The conversion of electrical energy into heat and light energy is a result of the filament's resistance to the flow of electrons.
