Transistor

Transistor¶

Gate: When voltage is supplied this is that switches the transistor on and off

N Channel: will flow voltage from Source (Voltage) to Drain (Load)
P Channel: will flow voltage from Drain to Source

Mosfet¶

Output is biased off of the input voltage

BJT (Bipolar Junction Transistor)¶

Emitter: output voltage
Base: low voltage switch input
Collector: input voltage

A small current at the base terminal flows between the base and the emitter, This switches a much larger current between the collector and emitter.

FET (Field Effect Transistor)¶

A voltage at the gate can control a current between source and drain
