Thomas Edison

Thomas Edison chose tungsten as the filament material for his electric light bulb because of its high melting point, which allowed it to operate at high temperatures without melting. This made tungsten more durable and long-lasting compared to other filament materials available at the time, ultimately increasing the lifespan of the light bulb.

Thomas Edison is often credited with inventing the long-lasting light bulb in the late 19th century. However, there were other inventors such as Joseph Swan who also contributed to the development of the incandescent light bulb around the same time. Edison's design, with a carbon filament inside a vacuum-sealed glass bulb, became the most commercially successful.

The invention of the phonograph was very important to society. The invention itself was very useful during the time of Edison and has impacted many similar inventions that have proved to be useful today.

Thomas Edison used tinfoil sheets wrapped around a metal cylinder to make the first sound recordings. The tinfoil would vibrate in response to sound, etching the sound waves onto it which could be played back by re-tracing the etchings with a stylus.

It is believed that Thomas Edison's barn burned down due to a cauldron experiment he was conducting in the barn. The experiment involved attempting to extract rubber from goldenrod plants, which led to a fire. Despite the barn burning down, Edison reportedly viewed it as a learning experience and rebuilt the facility as a research laboratory.

The first phonograph, a device for recording and reproducing sound, was built by Thomas Edison in 1877. It revolutionized the music industry by allowing sound to be recorded and played back for the first time.

there were three reasons, first, an effective incandescent material, next he was able to achieve a higher vacuum and third a higher resistance lamp that made power distribution from a central source an economical proposition

It depends on the condition of the record and the title. Is the record playable? Is it chipped or cracked? Is part of the plaster core missing? A good guess would be $5 for an average record with box and lid that match the title of the record. Others can be more valuable according to rarity and demand.

The lifespan of a light bulb varies depending on the type of bulb and how often it is used. Typically, incandescent bulbs last around 1,000 hours, while LED bulbs can last up to 25,000 hours or more. Factors such as wattage, quality of the bulb, and usage patterns all contribute to how long a light bulb will last before burning out.

No, Thomas Edison did not invent the baking soda volcano experiment. The baking soda and vinegar reaction, which produces a bubbling effect similar to a volcano, has been known for centuries. It is a simple chemical reaction that demonstrates the release of carbon dioxide gas.

Yes, Thomas Edison faced many challenges and failures while working on his inventions. He famously said, "I have not failed, I've just found 10,000 ways that won't work." Despite setbacks, he persevered and eventually achieved great success with inventions like the light bulb and phonograph.

The light bulb was invented by Thomas Edison in Menlo Park, New Jersey in 1879. Edison's invention revolutionized the way people light their homes and businesses.

If you have recently purchased light bulbs for your light, it is probably because you have bought the wrong voltage bulb. There are several different types of MagLites and each one must match the voltage of the batteries to the voltage of the bulb.

For example: If you bought a 3v bulb (2-cell) and put it in a 4-C Maglite, you'll blow the bulb

(4 batteries x 1.5v = 6v total)

There are two types of brand-name bulbs for incandescent (non-LED) Maglites. The original OEM bulb was a Krypton bulb and the newer, brighter bulbs are Xenon. They are available for all two through six cell C and D size Maglite flashlights.

Krypton bulbs

LWSA201 - 2-Cell Krypton

LWSA301 - 3-Cell Krypton

LWSA401 - 4-Cell Krypton

LWSA501 - 5-Cell Krypton

LWSA601 - 6-Cell Krypton

Xenon bulbs

LMSA201 - 2-Cell Xenon

LMSA301 - 3-Cell Xenon

LMSA401 - 4-Cell Xenon

LMSA501 - 5-Cell Xenon

LMSA601 - 6-Cell Xenon

Sir Humphry Davy did not invent the light bulb; it was actually Thomas Edison who is credited with its invention. Davy did work on the development of electric lighting, but he faced challenges such as finding a suitable filament that could produce a bright and long-lasting light. He experimented with various materials before the eventual success of Edison's carbon filament design.

A webermeter is an instrument used for measuring the flow rate of water. It typically consists of a dial or digital display that shows the volume of water passing through a pipe in a given time period, usually in gallons or cubic feet. Webermeters are commonly used in residential and commercial properties to monitor water usage.

Thomas Edison did not invent the motion-picture projector. He is credited with inventing the phonograph and the incandescent light bulb, but the motion-picture projector was actually invented by Thomas Armat and C. Francis Jenkins in 1895.

In the olden days without a light bulb, people relied on natural light during the day, candles, oil lamps, or gas lamps at night. This limited their activities after dark and made tasks like reading or working more challenging. Overall, life was slower-paced and people tended to sleep earlier.

Menlo Park is in California.

Thomas Edison is credited with inventing the first commercially practical incandescent light bulb in 1879.

The invention of the light bulb revolutionized the way people live by extending the hours of daylight, enabling activities to continue after sunset, and improving safety. It also paved the way for advancements in technology, such as the electric power grid and electronic devices that rely on electricity. Additionally, the light bulb has had a significant impact on industries, economies, and the environment by reducing the reliance on other sources of lighting like candles and gas lamps.

Thomas Edison only made one major discovery in physics, The Edison Effect. It made vacuum tubes work, which later made radios and television sets work. Some of his inventions came about by combining things that already existed. He put liquid bees wax on paper and created wax paper. Now we keep food fresh by plastic bags. Thanks Edison. He invented the voting machine. He invented the stock ticker. He invented the teletype, now the internet. Most of his inventions enabled things that already existed to be used on a wide scale. The electric light bulb already existed. He redesigned it so that it could work at higher voltages. That way, the source of electricity could be miles away, not in the same building. He redesigned the typewriter so it could be used as a business machine. Now you can use a keyboard on your computer. He improved the battery. I have no intention of listing the several hundred things he invented.

Places exist that have museums displaying his inventions. Try Ft. Myers, Florida, or Menlo Park, New Jersey. There are several more.

Thomas Edison improved the incandescent light bulb by developing a longer-lasting and more practical version that could be used for commercial and residential lighting. He also patented the first commercially viable incandescent light bulb.

The first commercially practical incandescent lightbulb was invented by Thomas Edison in 1879. It is often reported that the cost of the first lightbulb was around $1, which was quite expensive at that time.
