About This Chapter

Watch video lessons on electrostatics and learn about electric force fields, Coulomb's Law, capacitance and more. These video lessons are short and engaging and make learning easy!

Electrostatics - Chapter Summary and Learning Objectives

Examine repulsion and attraction of electric charges in this chapter, which also introduces you to electric force fields and electric potential. You'll learn to use Coulomb's Law and solve capacitor problems. Lessons in this chapter cover arrow direction and spacing and the strength of an electric field. When you've watched the lessons in this chapter, you'll understand:

  • Definition of electric force
  • Reasons some materials become charged
  • Polarization of neutral objects
  • Relationship between capacitance, charge and voltage

Video Objectives
Electric Charge and Force: Definition, Repulsion & Attraction Understand the atom, electrons and protons and describe why some materials become charged. Discuss how repulsion and attraction work.
Electric Force Fields and the Significance of Arrow Direction & Spacing Use field models to elaborate on repulsion and attraction concepts. Discuss the significance of arrow direction and spacing.
Coulomb's Law: Variables Affecting the Force Between Two Charged Particles Define Coulomb's law and discuss variables that affect the force between two charged particles. Discuss polarization of neutral objects.
Strength of an Electric Field & Coulomb's Law Use Coulomb's Law to show that the strength of an electric field is independent of the magnitude of a charge placed in the field.
Electric Potential: Charge Collections and Volt Unit Explain charge collections and how a charged particle can have the potential to do work. Understand why the volt is a unit of electrical potential.
Capacitance: Formula, Units and Calculations State the unit of capacitance and explain how it relates to charge and voltage. List and explain the factors determining capacitance and solve parallel-plate capacitor problems.

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.

Strength of an Electric Field & Coulomb's Law

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.

Electric Potential: Charge Collections and Volt Unit

5. 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.

What is Capacitance? - Definition, Equation & Examples

6. What is Capacitance? - Definition, Equation & Examples

Capacitors are used to store and quickly release large amounts of electrical energy. In this lesson, we will learn how capacitors are created and used and how your body can function as a capacitor.

Capacitance: Units & Formula

7. 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.
