After that, the flow continues towards the P region. They are – Collector, Emitter and Base.ĭue to the connection the bias formed and the holes started flowing from N junction. In the NPN configuration of a transistor, two types of diodes are used: N-P & P-N.Īs mentioned earlier, a transistor has three Terminals. One is the Base Current another is the Collector current.īut 2% of the total current flows in the IB, so IB is negligible. Now, the current through the emitter is known as Emitter Current which goes into two side.
The rest of the holes again flow towards the N. After that, the flow continues towards the N region. Now, the EB junction becomes the reverse biased and the CB junction becomes revere bias.ĭue to the connection the bias formed and the holes started flowing from P junction.
In the PNP configuration, the transistor P junction has many holes, and the intermediate junction called N has efficiency and electrons. The transistor consists of three section. In P-N-P transistors, two types of diodes are assembled here. There are three leads in a transistor, labeled as Base (B), Collector(C), and Emitter (E).There are two types of standard transistors, which are bipolar PNP & NPN.A Bipolar junction transistor (BJT) has two PN junctions for its functioning.Bipolar junction transistor is a current controlled device.Electrons, as well as the holes, act here as charge carriers.” “ A BJT is a type of transistor, has both electrons and holes. Transistor Type Bipolar Junction Transistor (BJT)
