6/22/2023 0 Comments Importance of transistor biasing![]() ![]() Power is the total amount of water flowing in given time. In general terms, charge is water, voltage is the pressure of water, current is the flow of the water. Read article voltage Water Analogy of Electricity The water analogy for electricity is useful in order to understand the concept of potential difference and for explaining voltage, current, and power. The depletion layer plays a very important role in the characteristics of the diode. This layer is produced at the time of manufacturing the diode. This layer acts like a barrier that opposes the flow of electrons from N-layer and holes from P-layer. The two junctions have the same potential barrier Depletion Layer In the depletion region or depletion layer of a PN junction diode immobile charge carriers +ve and -ve ions are present.The junction between base layer and collector layer is called as base-collector junction or b-c junction.The junction between emitter layer and base layer is called as e-b junction.There are two junctions in this transistor – junction J1 and junction J2.So it has largest number of charges (holes). Read following points to understand the process easily –electrons). So it has a very few number of charges (To forward bias a PNP transistor it is connected as shown in the above circuit. ![]() So it has medium number of charges (holes). Area of base layer is smallest and it is very thin layer.The area of collector layer is largest.Schematic of PNP Transistor Important Points about NPN transistor The n-layer is sandwiched between two p-layers. The PNP transistor consists of three semiconductor layers: two p-type layers and one n-type layer.
