Ch 12: Praxis Physics: Electrical Forces & Fields

About This Chapter

This chapter may serve as a valuable resource in your studies of electrical forces and fields in physics. You may use these lessons as part of your studies for the Praxis Physics exam.

Praxis Physics: Electrical Forces & Fields- Chapter Summary

In these lessons, you will have the opportunity to review different electrical charges, forces, and fields in preparation for any pertinent questions on the Praxis Physics exam. Additional topics that will be covered in this chapter include:

  • Arrow direction and spacing
  • Coulomb's Law
  • Qualities of insulators and conductors
  • Gauss' Law

These lessons come in the form of short videos and are accompanied by full transcripts. If you wish to jump to a specific point in the videos, you may use the video tag to skip directly to your desired topic. After you finish reviewing each lesson, you may take a brief multiple-choice quiz that will help you gauge how well you comprehend the covered topics.

Electric Charge and Force: Definition, Repulsion & Attraction

1. Electric Charge and Force: Definition, Repulsion & Attraction

Have you ever wondered what electricity is and where it comes from? Have you ever been zapped by static electricity and wondered how it got there? We'll answer all of these questions in this lesson on electric charge and force!

Electric Force Fields and the Significance of Arrow Direction & Spacing

2. Electric Force Fields and the Significance of Arrow Direction & Spacing

Did you know that force fields don't just exist in science fiction movies? In this lesson, we'll explore the electric force fields that surround charged particles and how we can draw diagrams that represent them.

Coulomb's Law: Variables Affecting the Force Between Two Charged Particles

3. Coulomb's Law: Variables Affecting the Force Between Two Charged Particles

In the 18th century, Charles Coulomb uncovered the secrets of electrostatic force between charged particles. The results of his experiments led to what is now known as Coulomb's Law, which tells us how force, charge, and distance are all related.

Insulators and Conductors: Examples, Definitions & Qualities

4. Insulators and Conductors: Examples, Definitions & Qualities

In this lesson, we'll explore the reasons that some materials conduct electrical energy with ease while others block it almost completely. We'll also talk about the property of conductivity and some everyday examples of insulators and conductors.

Gauss' Law: Definition & Examples

5. Gauss' Law: Definition & Examples

After watching this video, you will be able to explain what Gauss' Law is, derive Gauss' Law for a sphere and cylinder, and use it to solve problems. A short quiz will follow.
