# Ch 6: Electricity

Watch video lessons and learn about the different aspects of how electricity is generated and also how it works. The quizzes that follow each lesson can help you gauge your comprehension of the materials.

## Electricity - Chapter Summary and Learning Objectives

Electricity runs our world. Think about how lost you would be if there was no electricity. The thought might be enough to make you panic. Imagine trying to light a lantern or build a fire just so you have some light. Try getting your hair dry in the morning without the use of a blow dryer. Forget about trying to work without any computers. Electricity is everywhere. In this chapter, we will take a look at electricity, how it works and its components. You'll begin to understand more about this type of power that is such a large part of our world. In these lessons, you'll learn things like:

• Why some materials become charged and others don't
• What causes repulsion and attraction
• What makes a good conductor
• How batteries convert chemical energy into electrical potential
• What an electric current is
• Types of circuits
