About This Chapter
Electricity & Magnetism Concepts - Chapter Summary
The video lessons that you can find contained in this chapter are a great way to learn some important topics on electricity and magnetism. You can watch these lessons for clear and comprehensive overviews of the most significant electricity and magnetism topics.
Our lesson instructors will teach you about the key characteristics of electricity and magnetism that are relevant to the field of physics. You will also learn about some of the major scientific laws governing electricity and magnetism. Watch these lessons to learn about:
- The definition, repulsion and attraction of electric charge and force
- Examples, definitions and qualities of insulators and conductors
- Ohm's law
- Types of electrical power
- The energy conversion of voltage sources
- Magnetic forces and fields
- The definition of electromagnetic induction
Each lesson contains a practice quiz that will ask you questions on some of the main points of that particular topic. Once you have completed all of the lessons, the final chapter exam will help you determine what you remember about electricity. Your personal Dashboard will allow you to see what progress you have made as you complete each lesson.
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!
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.
3. 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.
4. 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.
5. Voltage Sources: Energy Conversion and Examples
We use them every day, but no one really gives them much thought. What are we talking about? Why, voltage sources, of course! Batteries and generators are two of the most common sources of voltage that power our daily lives. We'll look at them in detail to see how they work.
6. Magnetic Force: Definition, Poles & Dipoles
You're probably familiar with magnets, but have you ever stopped to consider how they work? In this lesson, we'll look at the root of magnetism and some of the fundamental properties of magnets.
7. What is a Magnetic Field?
Magnetic fields fill the space around all magnets, but they're impossible to detect with our own senses. We'll use a common tool to map out a magnetic field and then discuss ferromagnetic materials to see how a magnetic field can be used to create new magnets.
8. Electromagnetic Induction: Definition & Variables that Affect Induction
We use electromagnetic induction every day, but do you have any idea what it is? In this lesson, we'll discuss this everyday phenomenon, the factors that affect its strength and its most common applications.
