# Ch 12: Electrostatics

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.
