Lesson: Transistors Physics • Third Year of Secondary School

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.
