It depends on the state law or statute where the employment occurs. For example, in Texas, the law is wide open for employers, in that an employer needs no more reason to terminate an employee than that they want to. In other words, in Texas, an employer does not need any reason to terminate you. Of course it is a two-way street, in that an employee is free to leave at any time, for cause, or just because he wants to. This may not be true in the state where you are employed.
What elements make a light bulb possible?
For an element to be eligible for a light bulb, it should be highly malleable and should have a very high melting point. Tungsten is one such element which is extensively used to make filaments of electric bulbs.
How much money did thomas Edison make from the light bulb?
10 cm! It's always 10! Hhahahahaha. yeah no.
Probably because of a BAD ground. If you have 12 Volts to the light, then the light isn't grounded properly. yes sir bad ground
Who was the builder of the first power station?
Originally it was George Westinghouses' idea, but he hired Volta to construct it. It was Pearl Street Power Station. It was started on September 4, 1882, In NYC. About 85 people had enough energy to light 5000 lamps. They were billed $5 per kilowatt hour, but now we pay 9cents per kilowatt hour. $5 is our time money.
Why would your dashboard lights not be working is it a fuse or light bulb?
Is your fuse blown? I have the same problem with my truck. Are any other lights out, or just the instrument panel lights? Often the fuse powers other things. For instance my instrument panel lights are out and so are my running lights. I have found that I have a short somewhere in the wiring. If you replace the fuse and it blows again It is probable that you do as well. I am not sure that the instrument panel is a bulb or not could be analog lights. I am working on the same problem now.
AnswerDid you install a radio>? It is a common mistake to use the instrument light wire as a ground. If not, It could be a fuse, the dimmer switch, or the bulb, as a rule, all the lights dont blow at the same time. Some cars use a dimmer module, newer and high end imports especially going back (in my experience to 92 and possibly earlier in imports).RELELNTLESS
fuses,dimmer switch,head light moduel,daytime running light sensor,night time running light sensor all been replaced. The dashlights,nor any of the turn signals will come on AT NIGHT?? WHAT WOULD CAUSE THIS/
Thomas Edison's great brain invented the devise that we use today which is the light bulb.
Why couldn't Thomas Edison hear with his left ear?
Thomas Alva Edison could not hear with one of his ears, because he was part deaf. The question arises- why Edison, with thousands of brilliant discoveries to his credit did not invent a hearing aid for himself? The answer was simple. He himself answered it. If someone is partly deaf, people will have to talk to him in a very loud voice. That means lies cannot be told to him, for fear of others learning that someone is telling lies to that poor deaf person. True, we cannot shout lies. Edison himself said that he was somewhat deaf and lucky, so that he had not have to hear any lies from anyone.
WHEN Edison invent the electricity?
Mr Edison did NOT invent electricity. Lighting is electricity and we know Edison did not invent THAT.
Edison invented a number of ways to USE electricity for human enjoyment, for example, the light bulb, and the record player.
Why do we need a complete circuit for the bulb to light?
Its a power source such as a battery - Wire from the Positive on the battery to one contact on the lamp and a wire from the Negative of the battery to the other contact on the bulb
How do you help edison with his luggage on poptropica?
you put them in order from shortest to tallest and then click the wood at the bottom
How was the DC electricity generator invented by Thomas Alva Edison significant?
What did Thomas Edison and Michael Faraday have in common?
Thomas Edison and MIchael Faraday both lived during the 19th century. They were both famous inventors. Edison grew up in America, however Faraday lived in England.
What are some words that describe thomas Edison?
smart, intelligent, sophisticated, curious, brilliant
What year did Thomas Edison patented his first invention?
Thomas Edison received his first patent, U.S. Patent 90,646, on June 1, 1869. This patent was for the electric vote recorder.
When was the first light bulb made?
No single person made the electric light bulb. So that means there is no one answer for when it was made. You can pick any date from 1800 for a rudimentary bulb, to 1910 for a much more practical bulb of the sort that is now being phased out for fluorescent and LED technologies.
The first electric bulb seems to have been invented in 1800 by an English scientist named Humprey Davy. He invented a type of battery. When he connected the wires from his battery to a piece of carbon, it glowed.
In 1860, the English physicist Sir Joseph Wilson Swan(1828-1914) set out to create a long-lasting and practical electric light. He used carbon paper and discovered that it worked well as a filament. However, it didn't last too long.
Charles Francis Brush manufactured some carbon arc lamps to light public areas in Cleveland, Ohio, USA around 1877. These were used for lighting a square, a few streets, a few large office buildings, and a few stores. Very few people used electric lights.
Eventually, in 1879, Thomas Alva Edison, the American inventor, made an incandescent light bulb that lasted over 1500 hours. He experimented using many different materials for just the right filament. He used a carbon filament in an oxygen-free bulb, and it lasted only 40 hours, but he eventually increased its lifespan.
Lewis Howard Latimer (1848-1928) was a member of Edison's research team. He improved the bulb by inventing a special carbon filament which he patented in 1881. In 1882, Latimer developed and patented a way to manufacture his carbon filaments.
In 1903, Willis R. Whitney invented a way of treating the filament so it would not darken the inside of the bulb as it was used.
In 1910, William David Coolidge (1873-1975) invented a tungsten filament. This lasted even longer than the previous filaments, making the light bulb much more practical.

How much is your Thomas Edison phonograph worth?
The value of a Thomas Edison phonograph can vary significantly based on factors like its model, condition, and whether it includes original parts or accessories. Generally, antique Edison phonographs can range from a few hundred to several thousand dollars. For a precise valuation, it's best to consult an expert or appraiser specializing in vintage audio equipment.
