Up at the top, there was a door. And beyond the door was a world I never could have imagined: the Kingdom of Fantasy! Along with my guide, a frog named Scribblehopper, I set off on an incredible adventure to save the Queen of the Fairies. But along the way, I had to face giant scorpions, witches, sea serpents, pixies, and dozens of other creatures that I had only ever heard stories about. Holey cheese, what a journey!
A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit.he ratio of these currents varies depending on the type of transistor, and even for a particular type, varies depending on the collector current. In the example light-switch circuit shown, the resistor is chosen to provide enough base current to ensure the transistor will be saturated.
They stood on the shoulders of the great inventors of the 19th century to produce the greatest invention of the our time: the transistor. The transistor was invented in 1947 at Bell Telephone Laboratories by a team led by physicists John Bardeen, Walter Brattain, and William Shockley.he Transistor was probably the most important invention of the 20th Century, and the story behind the invention is one of clashing egos and top secret research.
