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.
Transistors are devices that control the movement of electrons, and consequently, electricity. They work something like a water faucet -- not only do they start and stop the flow of a current, but they also control the amount of the current.he point of contact was called a junction, thus the name junction transistor. With an electrical current applied to the center layer (called the base), electrons will move from the N-type side to the P-type side. The initial small trickle acts as a switch that allows much larger current to flow.
