About This Chapter
Overview of Electrostatics - Chapter Summary
Consult this series of short lessons to review the basics of electrostatics in physics. Taught by expert instructors, this chapter explores several topics related to electrostatics, including Coulomb's law, electric potential, electric fields and Faraday cages. You can work through the chapter at your own pace using any Internet-connected device. Take the accompanying self-assessment quizzes to see how well you understand these electrostatic concepts. Completing this chapter can help you:
- Describe repulsion and attraction as they relate to electric charge and force
- Understand the significance of arrow direction and spacing in electric force fields
- Summarize Coulomb's law
- Determine the strength of an electric field
- Assess an electric field's movement of charge
- Explain electric potential
- Identify the materials that are used in Faraday cages
- Solve physics problems that involve electric fields
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. Strength of an Electric Field & Coulomb's Law
After watching this lesson, you will be able to explain what an electric field is, distinguish between scalar and vector fields and use two electric field equations to solve problems. A short quiz will follow.
5. Electric Field & the Movement of Charge
After watching this video, you will be able to explain what an electric field is, draw electric field lines and vectors for charged particles, and complete calculations involving electric fields. A short quiz will follow.
6. Electric Potential: Charge Collections and Volt Unit
In this lesson, we'll find out that electric charges can be rather lazy until something motivates them to get work done. Find out what gives electric charges the potential to do work and how we measure that potential with something called voltage.
7. What is a Faraday Cage? - Definition & Material
Science is pretty amazing as you can see with experiments involving the Faraday cage. Read this lesson to learn how Faraday cages work and exist in everyday life.
8. Electric Fields Practice Problems
In this lesson, you will be introduced to electric fields so that you can practice calculating single fields, multiple fields, and electric fields in charged spheres. You'll also learn how Faraday cages work.
