2.11 Transistors Flashcards
1
Q
What is a transistor?
A
A high speed electronic switch. It has 3 legs and is a process device. A transistor is a semi-conductor; when switched OFF it insulates. when switched ON it conducts.
2
Q
When does the transistor switch ON?
A
It switches ON when the base V (V Base) is greater than 0.6V.
3
Q
What are the different legs on a transistor and what are they used for?
A
The Base leg is the switch, when it switches on it allows current to flow from Collector to emitter, this turning on an output device.
