Learning Objectives

Indicator: 2.5.2.LI.3 - Describe types inductor or as a passive electronic component

By the end of the lesson, learners can:

Define an inductor as a passive electronic component that stores energy in a magnetic field when current flows through it.
Identify and describe at least four types of inductors (air core, iron core, ferrite core, toroidal, and variable inductors) based on their core material and construction.
Explain the function of inductors in electronic circuits, including filtering, energy storage, and blocking alternating current while passing direct current.
Distinguish between an inductor and previously learned passive components (resistors and capacitors) by comparing their symbols, units, and functions.
Select an appropriate type of inductor for a given circuit application and justify the choice based on the inductor’s characteristics.

Exemplars (from the NaCCA curriculum)

Collaborative Learning: Using videos and pictures engage learners in mixed ability groups to undergo the following activities:
1. Define inductor
2. Outline the types of inductors
3. Explain the functions of inductors
Collaboration and communication:
- Engage learners to work in mixed gender groups to determine functions of inductors in a circuit
- Ensure all learners participate in all varieties of practical activities and project work given. Include mixed gender groupings as well.
