NPN Transistor – 2N3904
A transistor is basically an electrically controlled switch. There is an input, output, and a control line referred to as the emitter, collector, and base. When the control line (base) is triggered it will connect the emitter and the collector just like switching a switch. Since the power between the emitter and collector can be higher than the base, transistors are often used as amplifiers.
The 2N3904 is a NPN transistor meaning when power is applied to the base (control pin) it will flow from the collector to the emitter. Typically NPN transistors are used to “switch ground” on a device, meaning, they are placed after the load in a circuit.
