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.
What is the process by which light is produced by a light bulb?
Light is produced in a light bulb through a process called incandescence. When an electric current passes through the filament inside the bulb, it heats up the filament to a very high temperature, causing it to emit light. This process is known as incandescence.
What happens when electrons reach the light bulb?
When electrons reach the light bulb, they flow through the filament, generating heat and light. The heat causes the filament to glow and emit light. This process is known as incandescence, where the electrical energy is converted into heat and light energy.
How does a change in the size of the current through a bulb affect it's light output?
An increase in the current through a bulb will increase its light output because more current means more electrons passing through the filament, which generates more heat and light. Conversely, a decrease in current will result in lower light output as there are fewer electrons flowing through the filament to produce light.
What happens when electorns move through the filament of a light bulb?
When electrons move through the filament of a light bulb, they collide with atoms in the filament material, transferring energy. This energy causes the atoms to vibrate and release photons, which are the particles of light that we see. This process produces heat and light, which creates the illumination from the light bulb.
What happens when electrons travel through a filament?
When electrons travel through a filament, they collide with atoms in the filament material. These collisions cause the electrons to lose energy and heat up the filament, which then emits light. This process is how an incandescent light bulb produces light.

Is light the same as electricity?
Electricity is not the same as electric light. Electricity is the flow of electrons from one atom to the next. As electrons travel through the filament of a light bulb the resistance of the filament opposes the flow of current, which creates heat. The filament will heat up so much that it produces a visible 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.

Why does light appears when you flick the switch?
When you flick the switch, you complete an electrical circuit that allows the flow of electrons through the light bulb's filament. As the electrons pass through the filament, they collide with atoms, which causes the filament to heat up and glow, producing light. This process is called incandescence.
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.
Why is the filament in light bulb coiled?
The coiled filament in a light bulb is designed to increase the surface area of the filament. This helps to maximize the amount of light produced while also allowing it to reach a high temperature quickly, which is necessary for creating light through incandescence.
