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.
A capacitor is a passive electronic component which basically consist of two parallel metal layers separated by an insulator. The types of capacitors are named after this dielectric. We use capacitors with dielectrics made of ceramic, mica, polyester, tantalum etc. Capacitors are used to block or to store voltages and to filter out signals.
