If the emitter-base in forward biased then it offering a low internal resistance to the transistor. The emitter base biasing determining the internal resistance of the transistor. The base junction is connected with two other junction of collector and emitter. The large in size area of collector so it can able to collect most of the electrons supplied by the emitter.īase : The center junction of the transistor is known as the base. The collection section is moderately doped. The collector is like the receiver and emitter is the electron provider. Which controlling the number of electrons the emitter section emits.Ĭollector : This pin section will collecting the majority portion of the charge carrier or the electrons are mostly collected by the collector pin. For more understanding, the emitter emitting the electrons to the base area. The emitter pin is connected to the forward bias with respecting to the base pin, so majority of charge carries to the base.

The each terminals of the diode is explained below.Įmitter : The pin emitter carries majority of charges. Expanded as Emitter, Collector and Base respectively. The transistor have three terminals named as the E, B and C. The main difference of the NPN and PNP transistor is the direction of the current.

The arrow indicating in the transistor figure is denoted as the direction of flow of conventional current in emitter to base in forward direction. The Symbol of PNP and NPN transistor shown given below. Similarly, If the two N type blocks are joined with P type semiconductor is known as NPN transistor. The two blocks of P type joined with the N type semiconductor is known as PNP transistor. The both transistor are designed with two blocks of either P-Type semiconductor of N-Type semiconductor. Transistors are in two types, namely NPN transistor and the other one is PNP transistor. When working a as a switching the transistor will turn on/off function.

While transistor working as amplifier it can able to transform the low quality signals to high amplitude signals. The emitter base junction of the transistor is connecting to the forward bias and collector base junctions to the reverse bias. The terminals of the transistor are named as Emitter, Collector and Base. The transistor is available in two types of PNP and NPN. Each of the section have the capability to transfer the electrical energy at different state. Typically the transistor contains three layers or three terminals.
