About This Chapter
Electrostatics & Charge - Chapter Summary
In this chapter, our instructors explain what Coulomb's law is and how it describes the force between two charged particles. A study of the electric field and electric potential energy is also presented, as is Gauss' Law and dipole fields.
Your study continues with a formula and explanation for the concept of capacitance. This chapter should enable you to do the following:
- Describe Coulomb's law and how it was discovered
- Differentiate between discrete and continuous charge distributions
- Solve electric potential energy problems using an equation
- Explain what Gauss' law is and use it to solve problems
- Define electric dipole
- Use capacitance equations to solve simple problems
Our short video lessons and quizzes are available for you to study at any time, 24 hours a day, seven days a week. If you have trouble as you work through the chapter, contact one of our instructors to help. You can use the video tabs feature in the Timeline to review just one part of a video lesson if you wish to skip back to a specific topic.
1. 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.
2. Electric Field: Discrete & Continuous Charge Distributions
This lesson discusses the electric field, which is a map of the electric force a test charge would experience at any given location in space. Different charge distributions produce different electric fields, but the individual bits of charge all produce fields in the same fashion.
3. Electric Potential Energy: Definition & Formula
After watching this video, you will be able to explain what electric potential energy is and use an equation to solve electric potential energy problems involving point charges. A short quiz will follow.
4. 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.
5. Dipole Fields: Definition & Examples
In this lesson, we will learn what a dipole field is, and how to calculate the electric field strength at different points in the field. We will also look at some example calculations.
6. Capacitance: Units & Formula
After watching this lesson, you will be able to explain what a capacitor is, define capacitance, and solve simple problems using capacitance equations. A short quiz will follow.
