Define NPN transistor operation by understanding its structure, where two n-type semiconductor layers surround a p-type layer. This configuration allows current to flow only when a positive voltage is applied to the base. Campus Component offers easy-to-follow resources that break down this concept, making it simpler for students and professionals to grasp how NPN transistors power co... https://www.campuscomponent.com/blogs/post/what-is-an-npn-transistor
