are very different from one another. 4. What phenomenon on tungsten led Thomas A. Edison to invent the incandescent lamp? - He experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. In 1879‚ Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb that could glow for over 1500 hours. 5. What do you call the vacuum tubes used in transistors radio?

genius inventor of the electrical age. His hundreds of inventions made him a giant public figure and very well known in America and around the world within the 20th century. Among Edison’s most famous inventions are the first practical long lasting light bulb and the phonograph which was an early sound reproducing machine that used cylinders to record as well as reproduce sound. He also helped refine and develop other inventions like motion picture cameras‚ the stock ticker and the typewriter. His inventions

Li-Fi(Light Fidelity) The Future Technology in Wireless Communication Abstract: Whether you’re using wireless internet in a coffee shop‚ stealing it from the guy next door‚ or competing for bandwidth at a conference‚ you have probably gotten frustrated at the slow speeds you face when more than one device is tapped into the network. As more and more people and their many devices access wireless internet‚ clogged airwaves are going to make it. One germen phycist.Harald Haas has come up with

We choose this subject because parallel connection is the best for houses. We will mention the equipment and the procedure of the circuit so it could be clearer. Also the energy that comes out is a renewable energy system. Introduction/Theory: parallel circuit: a closed circuit in which the current divides into two

the main component your eye would see in the lava lamp would be the “lava”. As most of us might know‚ its not actual lava; it is actually made out of different colored waxes. The wax will only form into blobs and separate when it is heated up by a light bulb. This is another component that is installed at the bottom of the lamp. If there is no heat source‚ the wax will never separated and will stay clustered at the bottom of the lamp. Turning it on and heating the wax however‚ makes it less dense causing

than other equipment; light has longer usage than other equipment‚ especially for incandescent lamp. Many people still using incandescent lamp at their house‚ particularly for villager. They use incandescent lamp because is cheaper than the saver energy lamp like Phillips lamp for example‚ maybe it is more expensive than incandescent lamp‚ but the saver energy lamp have longer usage lifetime than incandescent‚ and it is brighter than incandescent lamp. But actually incandescent lamps have bigger power

have been many major inventions within the late 19th and early 20th century. Throughout history‚ these inventions have made great impacts on society. Three of these inventions that made the greatest impact are the telephone‚ the telegraph‚ and the light bulb. Each of these inventions has made a different impact in some way but they are still some of the greatest inventions. The telephone has left a huge impact on the world. The telephone is a device that can electronically transmit speech. Telephones

Thomas Edison was a man who influenced America more than anyone else. Some of the inventions he pioneered are still used to this day. He was a man who spent almost his entire life working as a scientist‚ and receiving more than 1‚200 patents in his lifetime. (Anderson pg.7) Thomas Edison’s life was probably twice as productive as a modern day chemist‚ he was a firm believer of an eight hour work day‚ eight hours in the morning‚ and eight in the afternoon. Aside from his amazing history as an adult

other electro-technical products. In 1895 Gerard’s younger brother Anton began working at the factory. With the help of Anton‚ the light wire bulbs he designed began to be produced in mass quantities‚ helping the company begin to expand. By 1920 they were mass producing cathodes and high output vacuum tubes for use in radios. Phillips did not just produce tubes and light bulbs; Philips was one of the first to build a radio transmitter and transceivers. On March 11‚ 1927 Phillips introduced the first nationally
