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.
Although both are transistors, they have significant differences in characteristics. BJT (Bipolar Junction Transistor). BJT is a type of transistor that consists of two PN junctions (a junction made by connecting a p type semiconductor and n type semiconductor).These two junctions are formed using connecting three semiconductor pieces in the order of P-N-P or N-P-N.t is a type of transistor, which can handle a higher amount of power and has a higher switching speed making it high efficient. IGBT has been introduced to the market in 1980s. IGBT has the combined features of both MOSFET and bipolar junction transistor (BJT).
