No, movable type is an invention that greatly precedes Thomas Edison. It was invented centuries earlier by Gutenberg.
thomas Edison didn't exactly "improve" the light bulb; he created a new type called an electric light bulb... ok so maybe he did improve it...
That would depend on the type. Thomas Edison invented the incandescent bulb. Nikola Tesla invented the florescent bulb (before Edison by the way). Ed Zubler invented the halogen.
About l877. the earliest Edison phonographs were the cylinder type. Disc recordings (hence the term Disk Jockey) were invented by Emil Berliner much later and he sold the patents to Columbia Records. We still have both Columbia records and CBS. Mr. Berliner was a US citizen who also developed the Microphone and related devices for recording purposes.
thomas edison did not invent the electric incandescent lamp it was sir joe swan but thomas edison invented one with the E type fitting the most commons fitting is E27 used in domestic applications. but avg life for lamps are as follows. incandescent 1000 hrs CFL 5000 HRS metal halide 1200HRS HPS 2600 hrs led (light emitting diode) 50000 hrs
The name of the scientist who invented AC electricity is Nikola Tesla. Thomas Edison fiercely competed with Tesla over the type of current energy grids would use. Edison lost the 'war of currents' because his DC electricity was impractical for long range energy transmission.
