Light Emitting Diode

-

 The history of the LED (light-emitting diode) bulb dates back to the early 1950s, when Nick Holonyak Jr., an engineer and inventor, first developed the technology. Holonyak created the first visible-spectrum LED, a red diode, while working at General Electric (GE). His breakthrough set the stage for the development of the LED bulb.

In 1962, Robert Biard and Gary Pittman, two Texas Instruments (TI) engineers, developed the first infrared LED diode. While Holonyak’s LED was visible to the human eye, Biard and Pittman’s LED was invisible. This was a significant step forward in LED technology, as it enabled the creation of sophisticated electronic circuits. In the 1970s, research into LED technology continued at a rapid pace. In 1972, M. George Craford, a scientist at Monsanto and TI, invented the first yellow LED, which was a major milestone in the development of LED technology. In 1976, T.P. Pearsall invented the first high-brightness LED, which was capable of producing light in a range of colors. By the 1980s, LED technology had advanced to the point where LED bulbs became commercially

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...

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...
