Abstract

Using GeoGebra to Enhance Student Understanding of Phasor Diagrams in AC Circuits Courses Siddharth Vyas, Ali Dehghan Banadaki, and Ali Shaban

Understanding, drawing, and interpreting phasor diagrams is an essential skill for electrical and mechanical engineers. Phasor diagrams are an important graphical tool that can be used to easily solve AC circuits that could sometimes be rather difficult to solve using mathematical equations. However, undergraduate electrical and mechanical engineering students continue to struggle with the concepts of phasor diagrams largely because of a lack of an easy to use and freely available drawing tool. Traditional lectures on phasor diagrams have relied on the use of pencil, eraser, graph paper, ruler, compass, and protractor. In addition to being difficult to use, the combined use of these tools is rapidly getting obsolete in the modern engineering world where simulation environments have almost entirely replaced physical drawing tools. This paper presents the use of GeoGebra an easy to use and freely available online drawing tool to teach phasor diagrams to undergraduate electrical and mechanical engineering students. The use of GeoGebra in teaching Statics and Mechanics course topics has been published and appreciated. This paper will present the use of GeoGebra in drawing phasor diagrams of AC circuits containing resistors, capacitors, and inductors. A distinct and important advantage of the use of GeoGebra in drawing phasor diagrams over paper drawn phasor diagrams is that GeoGebra allows the student to manipulate the phasor diagrams to test their conceptual understanding.
