This illustrates how the 2N3904 transistor is an amplifier. For a current gain of 100, a change in base current of 0.001 amps (a) results in a change of 0.1 amps at the collector.
The various parameters of the 2N3904 transistor are referred to as β or current gain, which is the ratio of collector current to base current. Depending on the circuit configuration, a load or equivalent load can be connected to the emitter or collector. The emitter and collector are the main terminals of the 2N3904 transistor. The 2N3904 transistor has three terminals: an emitter, base, and collector. A larger collector current can be generated by injecting a small base current into the 2N3904 transistor. This small transistor is the counterpart of the 2N3906 transistor, a positive-negative-positive (PNP) transistor. It can be used for audio signals and medium-speed switching applications.
The 2N3904 transistor is a bipolar negative-positive-negative (NPN) transistor usually suitable for negative ground circuits. We also provide you with a 2N3904 Datasheet pdf.
