how did people respond when Thomas Alva Edison showed light bulb invention?

They said, "it's just a fad... it'll never catch on."

Ok, deaf people have little lights in the corner that blink when the door bell rings. blind people can hear teh doorbell. Helen Keller must have had an electric collar that shocked her when it rang. \n\nsorry, my dad made it up and when he said it, it was so funny, idk how funny it is now.

isaac newton i mean sometimes he would sit on the end of his bed half dressed thinking about gravity\n\nor maybe edison he would find like 500 ways of not making a light bulb but all he would say is "i have not failed i have found 500 more ways to not make a light bulb work!"

Nikola Tesla.\n\nBecause he thought it wouldn't cause lights to flicker for anyone.

make and working elctric circuit like a bell, r a bulb, u can Also explain working of an electromagnet using a model.\nu can also expain the capillarity concept

No one invented electricity. It was discovered.\n\ntosmith

well, i imagine thomas edison had to use such breakers, and he preceeded westinghouse by more than a few years... a circuit breaker is merely an electrical switch, isnt it? \n\nand as edison was at teh forefront of electrical development in teh 1800's i suggest you look to his era.

Thomas Edison invented MANY things in his life:\n\n1. Incandescent lamp (aka the light bulb)\n2. Invented the microphone inside of telephones\n3. The locomotive train was a biggie.

Benjamin Franklin but a lot of scientists contributed in the discovery. It all started 600 BC with the greeks followed by Dr William Gilbert,Benjamin Franklin,Galvani and Volta,Michael Faraday,Thomas Edison and Joseph Swan,George Westinghouse and Nikola Tesla,James Watt and finally Andre Ampere and George Ohm

Both were extremely hard working and expected the same from assistants.\n\nTesla had much the better initial education and, arguably, the greater endowment of intellect.  He was more persistent than stubborn and much less given to pettiness.  I suspect he had far greater ethical standards.  He was not so focused on money, and had not Westinghouse greatly assisted him, his life might have been more obscure.\n\nTesla had much the better grasp of the limitless potentials within matter and electricity.  In many ways he presaged much of modern science, including things yet to be developed.\n\nThomas Edison was considerably more petty and cranky, though an astute manager of business affairs in comparison to Tesla.  He was an extremely hard worker and never let up once focused on developing something.  He is famous for his quotation that "genius is 1% inspiration and 99% perspiration" -- in other words, lots of hard work.  Edison is all the more remarkable for having had very little formal schooling.\n\nUndoubtedly, both were great self-learners.  Tesla's ideas prevailed in the electric power industry, and many remnants of his thinking are still being explored.  Unfortunately, there is a dearth of this material.  Tesla's remaining papers and inventions and apparatus were either destroyed or confiscated by the United States Government.\n\nIn their effects upon society, I tend to rank them as equals.  Both contributed to the age of electricity and electrical products about equally.\n\nAs people, I am much more interested in Tesla, and would prefer to work under such a person were I young once more.  In the long run, Tesla is more intriguing, but I think Edison is much more famous with more ordinary people, especially in the USA.\n\nFor superior mind:  Tesla, without a doubt.

When you ask the question "Who invented electric power?", I presume you mean the electric power distribution that we know of today.\n\nOne of the primary contributors would be Nikola Tesla, a Serbian-American electrical engineer and scientist.  He along with the Westinghouse corporation developed the three-phase AC power distribution used around the world today.  Tesla and Westinghouse corp were also heavily involved in developing new generators and motors using three-phase power.  Edison was trying to promote a relatively inefficient DC distribution system at the same time, but failed to gain widespread support.  Though Edison did create inventions, such as the light bulb, that helped make use of the ever-growing power grid.\n\nI had not heard of Gennai Hiraga before, but sounds like a pretty interesting inventor as well.

Thomas Alva Edison did not invent Electricity. \n\nThomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman who developed many devices which greatly influenced life in the 20th century. \nHe was one of the first inventors to apply the principles of mass production to the process of invention, and can therefore be credited with the creation of the first industrial research laboratory.\n\nHistory of electricity - \n\nThe ancient Greeks and Parthians knew of static electricity from rubbing objects against fur.\n\nThough Benjamin Franklin's famous "invention" of electricity by flying a kite in a thunderstorm turned out to be more fiction than fact, his theories on the relationship between lightning and static electricity sparked the interest of later scientists whose work provided the basis for modern electrical technology. Most notably these include Luigi Galvani (1737–1798), Alessandro Volta (1745-1827), Michael Faraday (1791–1867), André-Marie Ampère (1775–1836), and Georg Simon Ohm (1789-1854).

Thomas Alva Edison invented the light bulb, the phonograph, automatic telegraph, motograph, paraffin paper(which was used to wrap candy), electric pen, carbon rheostat, microtasimeter, sockets, switches, insulating tape, gummed paper tape, magnetic ore separator, life-sized electric railway, motion picture camera, steel alkaline storage battery, and many other things.  He had 1,368 different patents.

Early observations\nIn 1839, Alexandre Edmond Becquerel observed the photoelectric effect via an electrode in a conductive solution exposed to light. In 1873, Willoughby Smith found that selenium is photoconductive.\n\n[edit]\nHertz's spark gaps\nHeinrich Hertz, in 1887, made observations of the photoelectric effect and of the production and reception of electromagnetic (EM) waves, published in the journal Annalen der Physik. His receiver consisted of a coil with a spark gap, whereupon a spark would be seen upon detection of EM waves. He placed the apparatus in a darkened box in order to see the spark better; he observed, however, that the maximum spark length was reduced when in the box. A glass panel placed between the source of EM waves and the receiver absorbed ultraviolet radiation that assisted the electrons in jumping across the gap. When removed, the spark length would increase. He observed no decrease in spark length when he substituted quartz for glass, as quartz does not absorb UV radiation.\n\nHertz concluded his months of investigation and reported the results obtained. He did not further pursue investigation of this effect, nor did he make any attempt at explaining how the observed phenomenon was brought about.

he did not invent electric light\n\nThe first electric light was made in 1800 by Humphry Davy, an English scientist. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. This is called an electric arc.\n\nMuch later, in 1860, the English physicist Sir Joseph Wilson Swan (1828-1914) was determined to devise a practical, long-lasting electric light. He found that a carbon paper filament worked well, but burned up quickly. In 1878, he demonstrated his new electric lamps in Newcastle, England.\n\nIn 1877, the American Charles Francis Brush manufactured some carbon arcs to light a public square in Cleveland, Ohio, USA. These arcs were used on a few streets, in a few large office buildings, and even some stores. Electric lights were only used by a few people.

look at it this way. all things that happen to a persons life are products of the things he/she did in the past or is doing in the present. maybe you're thinking that your trying hard enough, but are you doing it right? Don't get tired of trying, just remember to always learn from your mistakes. \n\nme i always remember the story of thomas edison, when he was discovering the light bulb, he has tried 1000 (maybe more. i forgot the exact number) different materials for the lamp filament but still failed. his assistant told him that there is no hope in what they are doing because they failed 1000 times already. but mr edison said," we haven't failed 1000 times, we just discovered that these 1000 materials are not fit to be a lamp filament." after which he discovered the light bulb.\n\njust don't lose hope. i am very sure that all your hardship today will earn you something someday.
