SHS2 Applied Technology · Semester 2 Week 17: Electronic Components and Circuits

Lesson notes

Learning Objectives

Indicator: 2.5.2.LI.7 - Apply the principles and operation of transistors in designing circuits

By the end of the lesson, learners can:

Explain how the principles of transistor operation (current gain, switching, and amplification) inform the design choices made in a transistor circuit.
Test a transistor using a multimeter to distinguish a good NPN transistor from a faulty one and justify their conclusion.
Calculate the base current, collector current, and voltage gain of a simple common-emitter amplifier circuit given the component values.
Design and simulate a single-stage transistor amplifier circuit (e.g., voltage divider bias) using Multisim software, following a given design brief.
Assemble a working transistor amplifier circuit on a breadboard and verify its operation by measuring key voltages with a multimeter.

Exemplars (from the NaCCA curriculum)

Experiential Learning: Engage learners using a mixed ability grouping to:
- Select good transistors from faulty ones by testing and exhibit honesty in identifying good transistors from faulty ones. Project- based learning
- Design, simulate (using multism software) and construct amplifier circuits using transistors e.g. voltage divider, class B and AB Push Pull exhibiting sense of responsibility in the care of tools and equipment given them.

Assessment (2.5.2.AS.7). The document marks these depth-of-knowledge levels for this indicator: Level 2 Skills of conceptual understanding; Level 3 Strategic reasoning.

Teaching and Learning Materials:
- Computers installed with multism software
- Resistors, Capacitors, Inductors
- multimeters
- the use of the internet
