SHS2 Physics · Semester 2 Week 2: Electrostatics

Lesson notes

Learning Objectives

Indicator: 2.3.1.LI.1 - Describe the structure and operation of capacitors.

By the end of the lesson, learners can:

Identify the basic structural parts of a capacitor (two conducting plates, dielectric material, and connecting leads) and label them on a diagram.
Describe the function of each part of a capacitor in storing electric charge.
Explain, in simple terms, how a capacitor charges and discharges in a circuit.
Classify at least four common types of capacitors (electrolytic, ceramic, polyester film, variable) based on their construction and typical use.
State at least two practical applications of capacitors in everyday devices found in Ghana.
