Module Overview

In this module, the concepts of electric charge and interacting forces between charges are discussed.  This module begins with a brief review of vector notations in both 2-dimension and 3-dimension to aid in the study of electric force vectors. Coulomb’s law is the main focus of the discussion on electric force. The force of repulsion as well as attraction between two point charges is studies first, followed by the discussion of the use of superposition principle in the treatment of net force acting on a point charge due to multiple charges. 

Introduction
 
Many first-year students have some knowledge of properties of charge and have studied vectors in secondary school mathematics. The use of a mathematical tool (i.e. vector) to describe a physical quantity (i.e. electric force) may be new to some, and hence is the pedagogical focus of this module. The step-by-step solved examples which demonstrate how fundamental law can be applies to solve problems will help students develop critical thinking and analytical skills in problem solving. The multiple choice questions (MCQ) are intended for self-formative assessment to gauge conceptual understanding of the materials covered in the module. The feedbacks given in MCQ will reinforce the relevant key concepts.
 
This module consists of a sequence of 3 videos with 2 step-by-step solved examples and 10 self-assessment questions. It is expected that the course instructor, will supplement the module with additional questions and possibly one laboratory exercise.
 
Prerequisites
 
Before starting this module, it will be helpful to be familiar with:
  • Properties of protons and electrons,
  • Three-dimensional coordinate system,
  • Fundamental trigonometry.

Learning Outcomes

With careful study and problem-solving exercise, by the end of this module, one should be able to:
  • Use a charge model to explain the nature of electric charges and basic electric phenomena,
  • Represent electric forces in vector form,
  • Use Coulomb’s law to calculate the electric forces between charges.

Electromagnetics and Circuits

This project is a set of 12 learning modules that support the teaching of foundational level electromagnetics and circuits in engineering programs. These modules could be used for an inverted or hybrid delivery of a first year course, or courses. We envision these modules partially or fully replacing in-person lectures, and being paired with in-person laboratories and other hands-on experiential learning activities to create an effective, active learning experience.
