Lesson Plan: Transistors Physics • Third Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe how transistors can be used as electrical switches in circuits.
Objectives
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.
Prerequisites
Students should already be familiar with
- semiconductor junctions.
Exclusions
Students will not cover
- logic gates.
