In the late 1920's, Polish American physicist Julius Lilienfeld filed patents for a three-electrode device made from copper sulfide. There's no evidence that he actually created the component, but his research helped develop what today is a field effect transistor, the building block of silicon chips.

Transistor - Wikipedia

★ ★ ★ ★ ☆

A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power.It is composed of semiconductor material usually 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 ...

12/19/2016 · The transistor I used in this video is a BC557 PNP transistor. It’s one of the transistors that James Lewis recommends in his article on the best 4 transistors to keep in your parts kit. The photoresistor I used has about 10 kΩ when it’s light and 1 MΩ when it’s dark. The resistor on the base of the transistor is a 100 kΩ resistor.

★ ★ ★ ★ ☆

A transistor is an electronic component used in a circuit to control a large amount of current or voltage with a small amount of voltage or current. This means that it can be used to amplify or switch (rectify) electrical signals or power, allowing it to be used in a wide array of electronic devices.
