Ch 17: Chapter 17: Electricity - Holt Physical Science With Earth & Space Science

About This Chapter

The Electricity chapter of this Holt Science Spectrum - Physical Science with Earth and Space Science Companion Course helps students learn the essential lessons associated with electricity. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Electricity textbook chapter.

How It Works:

  • Identify the lessons in the Holt Electricity chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the electricity topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • The definition for electric charge
  • Qualities of insulators and conductors
  • How an electric field is defined
  • The definition and equation for electric potential energy
  • Types of electric current
  • Parts of an electrochemical cell
  • Kinds of electric circuits
  • The definition for electrical resistance
  • What electrical power is
  • How fuses and circuit breakers are different

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!

Insulators and Conductors: Examples, Definitions & Qualities

2. 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.

Electric Field & the Movement of Charge

3. 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.

Electric Potential Energy: Definition & Formula

4. 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.

Finding the Electric Potential Difference Between Two Points

5. Finding the Electric Potential Difference Between Two Points

After watching this video, you will be able to explain what electric potential difference is and calculate the electric potential difference between two points in a uniform electric field. A short quiz will follow.

Electrochemical Cells and Electrochemistry

6. Electrochemical Cells and Electrochemistry

Learn to identify the parts of and be able to describe an electrochemical cell, including the electrolyte, electrodes, anodes, and cathodes. Learn how to make a homemade lemon battery and how to diagram an electrochemical cell that will light a light bulb.

What is Electric Current? - Definition, Unit & Types

7. What is Electric Current? - Definition, Unit & Types

Like a river current is the flow of water molecules, electrical current is the flow of charged particles. In this lesson, we're going to explore what electrical current is, what causes it, and that, unlike a water current, electrical current doesn't always flow in one direction.

Electrical Resistance: Definition, Unit & Variables

8. Electrical Resistance: Definition, Unit & Variables

We'll take a shopping trip to the mall to learn how electrical resistance works and how it is affected by resistivity, conductor dimensions, and temperature. We'll also take a look at several common appliances that take advantage of resistance to function.

Electric Circuit Fundamentals: Components & Types

9. Electric Circuit Fundamentals: Components & Types

Electric circuits can be configured to power several loads, such as light bulbs, in series or in parallel. In this lesson, we'll look at both types of circuits and see how the voltage, current, and resistance are affected by installing additional loads.

What is Electric Power?

10. What is Electric Power?

Power is a word we use all the time, but do you really know what it means? We'll look at how electrical power relates to voltage, current and resistance and how knowing that relationship can help you in everyday life.

The Differences Between Fuses & Circuit Breakers

11. The Differences Between Fuses & Circuit Breakers

After completing this lesson, you'll be able to explain what fuses and circuit breakers do and describe the advantages of each. A short quiz will follow.
