12/2/2023 0 Comments Define transistor and its types![]() The condition that results in the various operating modes are decided due to the junctions formed at the emitter base and the collector base. Hence the variations at the base can constitute large amount of current at the collector. ![]() This paved the way for the generation of collector current. These few amounts of electrons get interacted with respect to the holes at the base whereas the left over amount of electrons can be seen moving towards the collector. This is the reason there will be the lesser amount of charge carriers like electrons are less in amount in comparison with that of the emitter. As we already know that the base present in the transistor has always lightly doped. The base current is also responsible for creation of vacancy at the collector. This current tends to flow towards the collector and in response the electron movement is observed in the collector region from base. This is the reason for the constitution of the base current that tends to flow through the region of base. Because of the forward bias condition at the emitter base junction there is the majority of the carriers entered in to the base. ![]() It has the capability of handling the high values of voltages and the greater ranges of currents.Īs it is known that the emitter base junction must be in forward bias and the collector base junction remain in reverse bias. ![]() The silicon is less sensitive to the temperature. The element named silicon is generally preferred for transistor construction. The doping consistency of the collector is moderate but the size of it is large compare to that of base and emitter.The above are the terminals present in the basic transistor. Hence it is considered for the collection of outputs this is the reason the interacted part of collector and base remain in reverse bias. As the name suggests it acts like a collector of the majority of the carriers. ![]()
