PARALLEL PLATE CAPACITOR WITH ADJUSTABLE CAPACITANCE

Problem:

In university education, main aim is to teach the technical details and the theory of a topic with examples, or tutorials to be shown. In the case of Capacitance topic of Physics courses, the experimental setups are expensive, might be dangerous for class usage and unnecessarily complex for the level of the students.

Technology:

“The Adjustable Capacitance Parallel Plate Capacitor” Experiment Setup is based on a well-known pedagogical example. Instead of using complex measuring devices, the system provides a variable capacitance which can be measured by simple multi-meters that are already available at laboratories. The systems geometry enables students to measure capacitance of a parallel plate capacitor with variable surface areas and plate to plate distances. Using these properties, students can measure the electric permittivity of air or any dielectric material.

Advantages:

•Easy to produce

•Contains no danger for class usage

•Provides capacitance up to 400 microfarads which is measurable 

with simple multimeters

•Enables measuring electric permittivity of air and other dielectrics

•Easy to establish
