Ch 6: Fundamentals of Electricity

About This Chapter

This chapter looks at the fundamental components of electricity. You'll learn definitions of key terms while reviewing examples of their application. The concepts are presented in simple-to-follow lessons that allow you to study the videos and transcripts of the content at your own pace.

Fundamentals of Electricity - Chapter Summary

This chapter covers core elements of electricity and how it functions. The lessons zero-in on scientific concepts and terms central to the study of electricity while demonstrating how they work. If you're worried about getting lost, you can use the practice quizzes accompanying each lesson to measure your understanding topic-by-topic. By the end of the chapter, you can expect to have a better grasp on the following:

  • How materials become charged
  • The qualities and differences of insulators and conductors
  • How electric currents are defined as well as their forms and function
  • Electrical resistance and what can impact it
  • How Ohm's Law describes the relation between voltage, current and resistance

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.

What is Electric Current? - Definition, Unit & Types

3. 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

4. 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.

Ohm's Law: Definition & Relationship Between Voltage, Current & Resistance

5. Ohm's Law: Definition & Relationship Between Voltage, Current & Resistance

Did you know that electrical current is affected by the voltage and resistance in a circuit? In this lesson, we'll use Ohm's law, which tells us how current, voltage, and resistance are related, as we work through several electric circuit examples.
