Thomas Alva Edison and his famous inventions

-

 Thomas Alva Edison was an American inventor and businessman who is widely regarded as one of the most influential inventors of all time. He is credited with the invention of many important devices, including the phonograph, the electric light bulb, the motion picture camera, and the electric power system. Edison is also credited with helping to create the modern industrial research laboratory.

The life of Thomas Edison began in 1847 in Ohio. He was the youngest of seven children. His mother, Nancy Edison, was an accomplished school teacher who taught him at home. His father, Samuel Edison, was a successful businessman who owned a small business. Edison was curious and inventive from a young age. He was often found tinkering with mechanical devices, even building a working telegraph by the age of 12. Edison went on to become a prolific inventor and businessman. He is credited with more than 1,000 inventions, including the phonograph, the electric light bulb, the motion picture camera, and the electric power system. Edison’s invention of the phonograph allowed people to record and playback sound for the first time, while his invention of the electric light bulb changed the way people lived and worked. His invention of the motion picture camera revolutionized the entertainment industry

Capacitor

  A capacitor is an electronic device that is used to store electrical energy . It is made up of two conduct ive plates separated by an ins ulating material called a die lect ric . When charged , the capacitor stores energy in the form of an electro static field between the two plates . This stored electrical energy can then be released when needed . One type of capacitor is the electroly tic capacitor . These capac itors are made from two metal plates that are separated by an electroly te solution . This type of capacitor is used in DC circuits and can store a large amount of energy . Another type of capacitor is the ceramic capacitor . Cer amic capac itors are made from layers of ceramic material and are used in high - frequency circuits . They are usually small and can store less energy than electroly tic capac itors but can handle higher volt a...

  The history of the LED ( light - em itting di ode ) bulb dates back to the early 1950 s , when Nick Hol ony ak Jr ., an engineer and inventor , first developed the technology . Hol ony ak created the first visible - spect rum LED , a red di ode , while working at General Electric ( GE ). His breakthrough set the stage for the development of the LED bulb . In 1962 , Robert Bi ard and Gary Pitt man , two Texas Instruments ( TI ) engineers , developed the first infrared LED di ode . While Hol ony ak ’ s LED was visible to the human eye , Bi ard and Pitt man ’ s LED was invisible . This was a significant step forward in LED technology , as it enabled the creation of sophisticated electronic circuits . In the 1970 s , research into LED technology continued at a rapid pace . In 1972 , M . George Cra ford , a scientist at Monsanto and TI , invented the first ...

What is a Transistor

-
Image
  A transistor is a semic onductor device used to amplify or switch electronic signals and electrical power . It is composed of semic onductor material with at least three terminals for connection to an external circuit . A voltage or current applied to one pair of the transistor 's terminals controls the current through another pair of terminals . Because the controlled ( output ) power can be much larger than the controlling ( input ) power , the transistor provides amplification of a signal . The history of the transistor dates back to the 1920 s when semic onductor research began . The first trans istors were created in 1947 by William Shock ley , John Bard een , and Walter Br att ain at Bell Labs . They were made from a material called g erman ium . These early trans istors were point - contact trans istors , which were made from two closely spaced met...
