What Are The Two Types Of Transistors?

What Are The Two Types Of Transistors? Transistors are broadly divided into three types: bipolar transistors (bipolar junction transistors What is NPN and PNP transistor? An NPN transistor has a piece of P-type silicon (the base) sandwiched between two pieces of N-type (the collector and emitter). In a PNP transistor, the type of the layers
