NPN and PNP: What?! Transistors 101 - Adafruit Learning System
http://www.learningaboutelectronics.com/Articles/Difference-between-a-NPN-and-a-PNP-transistor So in a NPN Transistor it is the movement of negative current carriers (electrons) through the Base region that constitutes transistor action, since these mobile electrons provide the link between the Collector and Emitter circuits. This link between the input and output circuits is the main feature of … See more In the previous tutorial we saw that the standard Bipolar Transistor or BJT, comes in two basic forms. An NPN (Negative-Positive-Negative) type and a PNP (Positive-Negative … See more The construction and terminal voltages for a bipolar NPN transistor are shown above. The voltage between the Base and Emitter ( VBE ), is positive at the Base and negative at the … See more Then we can see that the transistor is a current operated device (Beta model) and that a large current ( Ic ) flows freely through the device … See more Then the voltage sources are connected to an NPN transistor as shown. The Collector is connected to the supply voltage VCC via the load resistor, RL which also acts to limit the maximum … See more how can i unlock a locked phone
