Lesson Plan: Capacitor Dielectrics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the effect of the size of a capacitor’s plates on the capacitor by how much they are separated and by what medium separates them.
Objectives
Students will be able to
- relate the capacitance, , of a capacitor to the area, , of its plates, the distance, , between the plates, and the permittivity, , of the dielectric material between the plates, using the equation ,
- describe qualitatively how the permittivity of the dielectric material between the plates of a capacitor affects the electric field between the plates.
Prerequisites
Students should already be familiar with
- ,
- ,
- the value of the permittivity of a vacuum.
Exclusions
Students will not cover
- energy stored in capacitors.
