# Ch 4: Modeling Electricity

Let us help you learn more about calculations, basic units and other concepts used to model electricity. Use these lessons and quizzes as a convenient, mobile study guide as you prepare for an upcoming test or homework assignment.

## Modeling Electricity - Chapter Summary

Our instructors will explain what energy is and how it is transferred between sources. You will learn how to calculate power and its unique relationship with the concepts of time and work. A discussion of electrical charge, static electricity and the unique properties of electrical current follows.

As you progress through the chapter, the concepts of electrical potential and electrical potential difference are introduced, along with the definition of an ampere and the calculation associated with it. Both ammeters and voltmeters will be discussed, and a lesson devoted to energy measurement units and how to convert them is provided. After you have reviewed these lessons, you should be able to:

• Describe how energy is transferred from one source to another
• Calculate power and understand its relationship to work and time
• Understand where static electricity comes from
• Define electrical potential difference
• Explain what an ampere is and where it can be found in the natural world
• Differentiate between an ammeter and a voltmeter
• Convert common energy measurement units

Our professionally-designed videos, lessons and quizzes help make your learning experience simple and engaging. Use the quizzes and tests to measure your understanding of the topic or to see which areas require additional review. If you have questions as you read through the chapters, contact one of our instructors for help. The lessons and quizzes are available for you to study and review at any time, seven days a week.
