The power rating for a light bulb (like "40 W") tells how much electrical power the light bulb uses. All of the power used by the bulb is either converted into light or heat. In an incandescent bulb, most of the energy becomes heat. In a fluorescent bulb, more of it becomes light.
On a lightbulb, there is a number that is followed by a W. That is the number of watts the lightbulb uses. A watt is a measure of how much energy the bulb uses every second. The more watts, the more energy the lightbulb uses every second. For you calculus types: Power is the derivitive of Work with respect to time

From what source does Sweden get most of its electrical power?
Nuclear powerplants
What is Pikachu's resistance?
electricity I think
What type of electrical waveform is produced by a Ferroresonant Power Supply?
Sine wave
In victorian times who invented the lightbulb?
Humprey Davy in 1800
Which the following devices does not utilize radio waves?
A lightbulb does not utilize radio waves. It emits visible light when connected to an electrical power source.
How does the battery in a torch work?
A torch, or flashlight, typically uses a battery to power the lightbulb. When the battery is inserted into the torch, it completes a circuit allowing the current to flow from the battery to the lightbulb, which then emits light. The chemicals inside the battery convert chemical energy into electrical energy, powering the lightbulb.
What are three home applications where electrical energy is converted to movement energy?
Electrical fan, Lightbulb & treadmill.
The power of lightblubs is measured in?
The power consumption of a lightbulb would be in watts.
What are the three examples of electrical energy?
Lightbulb lighting up. Electric fan rotating. Phone charging.
What are 5 different kinds of electrical inventions in the world?
electric motorelectric generator or dynamotoasterincandescent lightbulbfluorescent lightbulb
What is an example of mechanical energy to radiant energy?
An example would be a lightbulb, where electrical energy (mechanical energy in the form of moving electrons) is converted to radiant energy (light). The electrical energy causes the filament in the lightbulb to heat up and emit light energy.
What is a device that transfers electrical energy to light and heat and sound?
An incandescent lightbulb is an example of a device that converts electrical energy into light and heat. A loudspeaker is a device that converts electrical energy into sound.
How do you change the headlights on a 2001 Honda Passport?
Headlights on the passport are easy to change. The headlamp assembly is composed of the housing, lens and lightbulb itself. Only the lightbulb needs to be changed. The electrical leads that connect to the lightbulb are removed in a "twist-and-turn" action. Unplug the lightbulb, unscrew it to pull it out of the assembly. Reverse the process to install. Should take about 5 minutes.
How much light is used to power a lightbulb with a solar panel?
48,000 gigawatts
Does the brain has electricity?
Yes, it has a slight amount of electricity to power up a lightbulb
How can you disconnect your closet light without shutting power off?
Take lightbulb out
