About This Chapter
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.
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!
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.
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.
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.
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.
