WebJan 2, 2024 · NPN Transistors are three-terminal, three-layer devices that can function as either amplifiers or electronic switches. In the previous tutorial we saw that the standard Bipolar Transistor or BJT, comes in two basic forms. An NPN ( N egative- P ositive- N egative) configuration and a PNP ( P ositive- N egative- P ositive) configuration. WebDec 21, 2024 · How does a transistor work? For an example, we will show how an NPN transistor works. A simple way to view its function as a switch is to think of water flowing through a tube controlled by a Valve. Water pressure represents ‘Voltage’ and water flowing through a tube represents ‘Current’ (Figure 3).
