What is Static Electricity? - Definition, Causes & Uses

1. What is Static Electricity? - Definition, Causes & Uses

In this lesson you will learn what static electricity is, what causes it, and what conditions prevent static electricity from occurring. You'll also see some fun and interesting real world situations and applications that involve static electricity.

Creating Energy from Solar, Wind, and Water Sources

2. Creating Energy from Solar, Wind, and Water Sources

Much of what we do requires an energy supply. But where does this energy come from? Often we get it from natural sources, such as wind, water, and sunlight, and in this lesson, you'll learn how these can be converted to electricity for our everyday use.

Electric Charge and Force: Definition, Repulsion & Attraction

3. 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!

Coulomb's Law: Variables Affecting the Force Between Two Charged Particles

4. Coulomb's Law: Variables Affecting the Force Between Two Charged Particles

In the 18th century, Charles Coulomb uncovered the secrets of electrostatic force between charged particles. The results of his experiments led to what is now known as Coulomb's Law, which tells us how force, charge, and distance are all related.

Electric Potential: Charge Collections and Volt Unit

5. Electric Potential: Charge Collections and Volt Unit

In this lesson, we'll find out that electric charges can be rather lazy until something motivates them to get work done. Find out what gives electric charges the potential to do work and how we measure that potential with something called voltage.

Voltage Sources: Energy Conversion and Examples

6. 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.

What is Electric Current? - Definition, Unit & Types

7. What is Electric Current? - Definition, Unit & Types

Like a river current is the flow of water molecules, electrical current is the flow of charged particles. In this lesson, we're going to explore what electrical current is, what causes it, and that, unlike a water current, electrical current doesn't always flow in one direction.

Electrical Resistance: Definition, Unit & Variables

8. Electrical Resistance: Definition, Unit & Variables

We'll take a shopping trip to the mall to learn how electrical resistance works and how it is affected by resistivity, conductor dimensions, and temperature. We'll also take a look at several common appliances that take advantage of resistance to function.

Ohm's Law: Definition & Relationship Between Voltage, Current & Resistance

9. 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.

Series Circuits: Definition & Concepts

10. Series Circuits: Definition & Concepts

When you flip a switch to turn your lights on, you are completing a circuit and providing a pathway for electrons to flow. In this lesson, you'll learn how connecting devices in a series along that circuit affects the current and resistance throughout.

Parallel Circuits: Definition & Concepts

11. Parallel Circuits: Definition & Concepts

People moving through an airport are similar to electrons moving through a circuit. Parallel circuits are one type of simple circuit, and they get their name from the multiple, parallel paths they provide for electron flow.

What is Electric Power?

12. What is Electric Power?

Power is a word we use all the time, but do you really know what it means? We'll look at how electrical power relates to voltage, current and resistance and how knowing that relationship can help you in everyday life.
