# Ch 5: Electric Power & Electricity

Watch video lessons in your study of electric power, electric potential, electric force fields and applied electricity. These video lessons are short and engaging and make learning easy!

## Electric Power & Electricity - Chapter Summary and Learning Objectives

We all use it, but just what is electric power? Through these video lessons with quizzes, you can learn about electric current, the qualities of conductors and insulators, charge collections and electric force fields. In addition, you can find out about Ohm's Law and Coulomb's Law and discover what they teach us about electricity. When you're finished with this chapter, you should be able to:

• Discuss the fundamentals of electric circuits
• Explain various voltage sources
• Understand electric charge and force fields
• Discuss applied electricity
