Transistor Schaltplan. A voltage or current applied to one pair of the transistor s terminals controls the current through another pair of terminals. Jfets are voltage controlled transistors composed of 3 terminals.
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. Like a breadboard layout it is a way of showing how the. This small current is supplied by the arduino digital output.
A voltage or current applied to one pair of the transistor s terminals controls the current through another pair of terminals.
Most of the electricity flows from the collector to the emitter but this will only happen if a small amount is flowing into the base connection. Jfets are voltage controlled transistors composed of 3 terminals. The gate the drain and the source. The diagram below is called a schematic diagram.
