Where do the electrons that will light a bulb get the energy to produce the light?
There are many possibilities:
-- from the big generators at the power company's generating station, that
take the energy out of coal, oil, natural gas, uranium, or falling water;
-- from the little generator in your basement, that takes the energy out of gasoline;
-- from the little generator rubbing against your bicycle tire, that robs some of
the kinetic energy that you put into the wheel with your leg muscles;
-- from the wind farm outside of town, where windmills take the kinetic energy
out of moving air;
-- from the photovoltaic (solar) panels on the roof, that take the energy out of sunshine.
-- from a battery, that was previously charged up with energy when somebody
connected it to one of those other sources;
-- from a battery that has combinations of elements, compounds, moisture, and
metals inside that combine their chemical energy in ways that make electrical
energy available at the battery terminals. For a while.

Is it true a light bulb acts as resistor in the flow of electrons?
While a light bulb does not technically act as a resistor, in practice it does impede the flow of electrons due to its resistance. As electrons pass through the filament of the light bulb, they encounter resistance, which causes them to release energy in the form of heat and light. This phenomenon is what allows the light bulb to produce light.
When energy runs through a light bulb what kind of energy does the light bulb produce?
A light bulb uses electrical energy, and produces light, as well as heat.
What types of energy does a light bulb use?
A light bulb typically uses electrical energy to produce light. The electrical energy is converted into heat and light energy by the filament inside the bulb.
What type energy does a light bulb produce?
A light bulb produces radiant energy in the form of visible light. When electricity flows through the filament of a light bulb, it heats up and emits light.
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.
Does a light bulb produce light?
they produce protons and electrons they are collition then the light produce and heat produce

What does an energy saving light bulb do?
It uses less energy to produce the same amount of illumination as a standard light bulb
What type energy does a light bulb produce?

What does the light bulb do in a circuit?
Bulbs convert an electrical energy to produce light
Why a lamp produces energy and light?
A lamp does not produce energy; it converts electrical energy into light energy through the process of incandescence or by generating light via LEDs. In an incandescent bulb, electricity heats up a filament wire that emits light as it glows. LEDs produce light by electrons moving through a semiconductor material, which emits photons in the form of light.
Is it true that A light bulb converts electrical energy into both heat and light energy.?
Yes, it's true. When a light bulb is turned on, most of the electrical energy is converted into heat, but some of it is also converted into light energy. This is what allows the light bulb to produce light.
Why is a light bulb a example of light energy?
A light bulb is an example of light energy because it transforms electrical energy into light energy. When the light bulb is turned on, electrical energy flows through the bulb, causing the filament to heat up and produce light. This process demonstrates the conversion of one form of energy (electricity) into another form (light).
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.
