Both p-n-p and the n-p-n transistors are the basic transistors which come under the category of bipolar junction transistors. These are used in the various amplifications circuits and the modulating circuits. The most frequent one among its applications is it’s fully ON and the OFF operating mode which is referred to as switch. NPN and PNP transistors are bipolar junction transistors, and it is a basic electrical and electronic component which is used to build many electrical and electronic p … [Read more...]
