WebThe BJT is a current-controlled device where the o/p of the base terminal or emitter terminal is a function of the current in the base terminal. Fundamentally, the operation of a BJT transistor is determined by the current at the base terminal. This transistor consists of three terminals namely the emitter, base, and collector. http://www.learningaboutelectronics.com/Articles/Dc-analysis-of-a-bipolar-junction-transistor-circuit
