Transistor (pack of 5)
Transistor are a type of electronic switch used for controlling the flow of a circuit and amplifying signals.
They have three legs: the base, the collector, and the emitter.
NPN: When a voltage is applied to the base leg of the transistor it allows current to flow from the collector to the emitter. This means you can control a higher current path using logic level signals from a device like a micro-controller.
PNP: When a voltage is applied to the base leg of the transistor it prevents current from flowing from the collector to the emitter.
