Learning Objectives

Indicator: 2.5.2.LI.2 - Describe types capacitor as a passive electronic component

By the end of the lesson, learners can:

Define a capacitor and state its basic construction (two conducting plates separated by an insulating material called a dielectric).
Identify and describe at least four types of capacitors, including electrolytic, ceramic, polyester film, and variable capacitors, stating their key features and typical uses.
Explain at least three functions of a capacitor in electronic circuits, such as storing charge, filtering, and coupling or decoupling signals.
Read and calculate the value of a capacitor using the colour code system, presenting answers in picofarads (pF), nanofarads (nF), and microfarads (µF).
Distinguish between polarised and non-polarised capacitors and select the appropriate type for a simple circuit based on its function.

Exemplars (from the NaCCA curriculum)

Collaborative Learning: Using videos and pictures engage learners in mixed ability groups to undergo the following activities:
1. Define capacitor
2. Outline the types of capacitors e.g. Electrolytic, ceramic
3. Explain the functions of a capacitor
4. Calculate the values of capacitor using colour codes
Experiential Learning:
- Engage learners to work in mixed gender groups to use colour codes to calculate for the values of resistors and capacitors
- Ensure all learners participate in all varieties of practical activities and project work given. Include mixed gender groupings as well.
