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.

Jargon buster
Plain-language definitions for the technical terms used above.
- Power dissipation
- Power dissipation is electrical energy being turned into heat inside a component. It matters because too much heat can reduce efficiency, affect reliability, or require a larger component or better cooling.
