A Transistor is a semiconductor device with a base electrode, an emitter electrode and an collector electrode, that sandwiches dissimilar semiconductors such that can control current flow under certain conditions.

    • The collector accepts an input current from the circuit, but it can't send the current through the transistor until allowed to by the base.
    • The emitter sends a current out into the circuit, but only if the base allows the collector to pass the current through the transistor to the emitter.
    • The base acts like a gate. When a small current is applied to the base, the gate opens and a large current can flow from the collector to the emitter.

    • An NPN transistor uses a positive semiconductor material (P-type) for the base and negative semiconductor material (N-type)for the collector and emitter. On a circuit diagram, and NPN transistor shows an emitter with the arrow pointing out (Never Points iN).
    • A PNP transistor uses an N-type material for the base and P-type material for the emitter and collector. The PNP transistor show an emitter with the arrow pointing in (Points iN Permanently).
