2N3904, 2N3904 Datasheet, 2N3904 NPN General Purpose Transistor Datasheet, buy 2N3904 Transistor Figure 2: 2N3904 circuit example - drawn in Scheme-it®. Since the 2N3904 is an NPN transistor, that means the base needs positive biasing (appropriate voltage levels and resistance) to turn on the collector emitter junction for proper current flow.
