What’s the Difference Between PNP and NPN Transistors?

WebThe NPN transistor conducts current due to movement of electrons from low resistance region to high resistance region. PNP transistor conducts when holes move from low resistance to high resistance region. Both are the subtypes of the transistor and both are used in amplification or switching process. Web1.It has been determined that no problems, such as degradation or destruction, will arise from use. 2.In the case of an NPN transistor, B is symmetrical with C, and E with N. Therefore, C and E can be used as a transistor, even when connected in reverse. In this case current will flow from E to C.
