Npn And Pnp Transistor Diagram. Voltage allocation and current flow are switched. Bipolar transistor are given above with the arrow in.
When there is no voltage on base terminal it works as an open switch. The two types are pnp and npn transistors. Below we go over the concepts explained above in more depth with diagrams to better illustrate the differences between npn and pnp transistors.
