The first person known to have created an incandescent light bulb was Sir Humphrey Davy, British chemist and inventor. However, Joseph Swan and Thomas Edison were the first to make light bulbs that were practical and economically viable.
What else can I help you with?
Does the place where the light bulb is affect the heat given off?
does the vessel where the light bulb is placed affect the heat
Is heat given off by a light bulb chemical energy?
No, the heat given off by a light bulb is not considered chemical energy. This heat is a byproduct of the conversion of electrical energy into light energy and thermal energy in the filament of the bulb.
What are waves given off by a light bulb?
mostly light and heat (infrared)
What forms of energy are given off by a light bulb?
A light bulb gives off mainly light energy as well as heat energy. When electricity flows through the filament in the bulb, it gets hot and emits light.
4 Who invented the light bulb and what year was it invented?
The light bulb was invented by Thomas Alva Edison in 1879.
How long did it take Albert Einstein to make the light bulb?
Albert Einstein did not invent the light bulb; that credit goes to Thomas Edison. Einstein, a theoretical physicist, is known for his work on the theory of relativity and his contributions to the field of physics, but not for inventing the light bulb.
Did michael faraday invent the light bulb?
No he did not. He is associated with the invention of pasteurisation. He also invented some vaccinations. Thomas Edison is generally given credit for inventing the light bulb, though others had created them before he did.
Where does the energy given off by the light bulb come from?
From the electric current that powers it.
When compared in a given time interval with other light bulbs connected to a 120 V circuit a 60 W lightbulb?
A 60 W light bulb consumes more power (produces more light) than a 40 W light bulb in a given time interval when both are connected to a 120 V circuit. This is because power is directly proportional to the wattage rating of the light bulb.
What is the regular light bulb called?
Assuming you mean the type that was invented by Thomas Edison, it is the Incandescent Bulb. Light is given off by a coiled Tungsten filament that is heated by an electric current flowing through it. The amount of light given off is rated in Lumens, but most generally the consumer relates it to "Wattage". The higher the wattage the more light given off.
How much of the electrical energy used to light an incandescent bulb is converted into light energy?
Only about 10% of the electrical energy used to light an incandescent bulb is converted into light energy. The rest is mostly given off as heat.
What happens to the energy wasted by the light bulb?
The wasted energy by a light bulb is primarily given off as heat. This heat is dispersed into the surrounding environment, contributing to the overall temperature of the room.
