There are two important parameters of a transistor: the (α) and the (β). The relation between emitter current Ie and the collector current Ic is given by the parameter, known as alpha (α) of the transistor.
Read MoreParameters of Bipolar TransistorThe PNP transistor can be used in two different modes: forward biased mode and the reverse biased mode. In forward biased mode, the current can easily flow through it. So it acts like a CLOSED SWITCH.

Bipolar and unipolar transistors can be categorized according to their basic functionality. In bipolar transistor the electric current flows due to BOTH electrons and holes through it. However, in unipolar transistor the current flows EITHER due to electrons OR holes through it.
