## Transistors
|
|
|
|
Two types of transistors will be discussed here: `NPN` and `PNP`.
|
|
Both types however, do share some properties here by referred to as the following:
|
|
|
|
* E = Emitter
|
|
* B = Base
|
|
* C = Collector
|
|
|
|
### NPN
|
|
|
|
When the base/gate is "on" we mean current can flow from the emitter to the collector.
|
|
|
|
### PNP
|
|
|
|
When the base/gate is "on" we mean current can _not_ flow from the emitter to the collector.
|
|
|
|
> When we say that a gate is "on" we're really saying that it's open.
