Ch 7: Electricity Generation & Transmission

About This Chapter

This chapter helps you review electricity generation and transmission. The video and text lessons can help you study for an exam, complete homework assignments, or prepare for a class discussion.

Electricity Generation & Transmission- Chapter Summary

This chapter includes lessons on how electricity is generated and transmitted. You'll review topics such as electrical power, alternators, and the generator effect. The lessons can also help you brush up on the use of electromagnetic induction and how generators and electric motors work. By the time you finish studying these resources, you should be able to:

  • Provide examples of different kinds of electrical power
  • Explain what mutual induction is and how it is used
  • Detail how electricity is generated
  • Make AC power calculations
  • Relate what an alternator is
  • Describe the generator effect and demonstrate it using graphs

The video lessons are short in length and come with a timeline feature that allows you to skip around to specific areas of the lesson. The text lessons and video transcripts include keywords in bold print for easy identification. Take the corresponding quiz when you've finished each lesson to make sure you've retained the material presented.

Electrical Power: Definition & Types

1. Electrical Power: Definition & Types

Curious about the different types of electrical power? In this lesson, we'll define DC and AC power, provide a few examples, and provide a quiz to check your understanding.

Electromagnetic Induction: Conductor to Conductor & Transformers

2. Electromagnetic Induction: Conductor to Conductor & Transformers

Every day, we make use of a special case of electromagnetic induction known as mutual induction. In this lesson, we'll talk about this special phenomenon and how it is used in many common devices.

Lenz's Law, Magnetic Flux and Motional EMF

3. Lenz's Law, Magnetic Flux and Motional EMF

Did you know that you can produce electricity by simply moving a magnet? In this lesson, learn more about electromagnetic induction and how electricity is generated.

Faraday's Law of Electromagnetic Induction: Equation and Application

4. Faraday's Law of Electromagnetic Induction: Equation and Application

Electromagnetic induction allows us to induce voltage with the movement of a magnetic field. Credited to Michael Faraday, this discovery was not only groundbreaking at the time, but it has since led to many applications in everyday life.

Alternating Current Power Calculations

5. Alternating Current Power Calculations

After watching this lesson, you will be able to explain the difference between AC and DC circuits and calculate AC current, AC voltage and AC power using both rms values and peak values. A short quiz will follow.

What Is an Alternator? - Definition & Description

6. What Is an Alternator? - Definition & Description

An alternator is a magical device that can turn mechanical energy into electrical energy. Okay, it's not actually magic, it's science! This lesson will explain how an alternator works.

Electric Motors & Generators: Converting Between Electrical and Mechanical Energy

7. Electric Motors & Generators: Converting Between Electrical and Mechanical Energy

Both generators and electric motors are common devices in everyday life, but how do they work and what is the difference between them? In this lesson, we'll explore both of them, which may produce different results but are actually more similar than they may seem.
