Bipolar Junction Transistors

Transistor types and polarities

Transistors are three-terminal devices capable of amplifying signals. They come in two broad classes, bipolar junction transistors (BJTs), and field-effect transistors (FETs). These notes are about BJTs.

Voltage and Current

Current (I) is the rate of flow of charge through a certain point in a circuit, it is measured in amperes. Voltage (V) between two points in a circuit represents the driving force that causes current to flow between them, it is measured in volts. Read More →
