Lesson: Transistors Physics

Start Practising

In this lesson, we will learn how to describe how transistors can be used as electrical switches in circuits.

Lesson Plan

Students will be able to

describe how the base, collector, and emitter terminals of PNP or NPN transistors relate to the semiconductor doping at these terminals,
describe how the currents at the terminals of a transistor vary with the bias applied to the transistor junctions by an external circuit,
manipulate the following equations in different combinations to calculate , , and : , , and ,
use in different combinations and describe how each term affects the others.
