Description
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.
The 2N3906 is a PNP transistor meaning when there is no current flowing between the emitter and the base (control pin) it will flow from the emitter to the collector. Typically PNP transistors are used to “switch power” on a device, meaning, they are placed before the load in a circuit.
