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.
Does a light bulb convert electrical energy into electromagnetic energy?
Yes, a light bulb converts electrical energy into electromagnetic energy in the form of light and heat. The electrical energy flows through the filament in the light bulb, causing it to heat up and emit light as a result of the electromagnetic radiation produced.
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 two forms of energy does a lightbulb produce?
A lightbulb primarily produces light energy through the emission of photons when electricity passes through the filament. It also produces a small amount of heat energy due to resistance in the filament that causes it to get hot.
What is the waste energy from a hairdryer?
The waste energy from a hairdryer is mainly in the form of heat and noise. The heat generated is a byproduct of converting electrical energy into thermal energy to dry the hair, while the noise is produced by the motor and airflow components within the hairdryer.

What is heat and how is heat produced?
Heat is a form of energy that makes things hot.

What form of energy is always produced when energy changes from one form to another?
Heat energy is always produced when energy changes from one form to another. This is due to the inherent inefficiencies in energy conversion processes, where some of the energy is lost as heat.
What electrical current flows through the metal filament of a light build electrical energy is converted to?
The electrical current that flows through the metal filament of a light bulb is in the form of electrons. As the electrons pass through the filament, they encounter resistance, which causes the filament to heat up and emit light. This process converts electrical energy into light and heat energy.
How is light bulb a form of energy?
A light bulb is a form of energy because it converts electrical energy into light and heat energy through the process of resistive heating of the filament inside the bulb. When electricity flows through the filament, it heats up and produces light as a result of incandescence.
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.
What is produced when electrons flow through the filament if a light bulb?
When electrons flow through the filament of a light bulb, they collide with the atoms of the filament material, causing them to heat up and emit light in the form of photons. This process is known as incandescence and is what generates the light produced by the bulb.
Which form of energy is produced when paper is burned?
The form of energy produced when paper is burned is thermal energy, due to the heat released during combustion.
