A transistor is a semiconductor device used for amplification and switching applications in electrical and electronic circuits. It consists of three regions: emitter, base, and collector. The transistor action is based on the principle of controlling the flow of current between collector and emitter using a small input current at the base. A transistor usually has two types: NPN and PNP, which differ in the arrangement of semiconductor layers and direction of current flow. In an NPN transistor, a thin p-type base is sandwiched between two n-type regions, whereas in a PNP transistor, an n-type base is sandwiched between two p-type regions. The working of a transistor can be explained by considering the NPN transistor. When the emitter-base junction is forward biased ________ _________ ________ _________ __________ ________.
