    PnP transistor is a current controlled device. It has two crystal diodes connected back to back. The left side of the diode is known as the emitter-base diode and the other side which is the right side of the diode is known as the collector-base diode.

    A transistor is of two types: PNP and NPN

    Explanation:

    A transistor is current controlled device in which the current flow by the movement of the electrons and wholes.

    The NPN and PNP transistor are the types of the BJT (Bipolar junction transistor) that have two uses i. e switching and amplification.

    A PNP transistor have three junction i. e P, N and P where the base is connected to the N - junction. The P junction is high in number of wholes and N - junction have high numbers of electrons.

    In the PNP transistor the voltage is provided to the emitter and base terminal with base connected to the negative terminal of the voltage source and emitter connected to its positive terminal. The direction of the flow of the current is from emitter to collector whenever a significant voltage is provided to the emitter base junction.
