Electronics Fundamentals/Semi Conductor Devices/Transistor/NPN Transistor

NPN Transistor
NPN Transistor is a Semi Conductor Device made from Semi Conductor materials which has 3 pins Base, Collector, Emmiter forming 2 junctions namely BE and CE

NPN Transistor
NPN Transistor is made by joining one Positive-Typed Semi Conductor in between two Negative-Typed Semi Conductors
