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. Electric Force Fields and the Significance of Arrow Direction & Spacing
Did you know that force fields don't just exist in science fiction movies? In this lesson, we'll explore the electric force fields that surround charged particles and how we can draw diagrams that represent them.
3. 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.
4. 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.
5. 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.
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.
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.
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.
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.
10. Electric Circuit Fundamentals: Components & Types
Electric circuits can be configured to power several loads, such as light bulbs, in series or in parallel. In this lesson, we'll look at both types of circuits and see how the voltage, current, and resistance are affected by installing additional loads.
11. 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.
12. Ampere: Definition & Calculation
This lesson will cover the definition of an ampere and provide practical examples of where you may encounter an ampere in everyday life. The calculation of amperes as it applies to current is also discussed.
13. Charles Coulomb: Discoveries & Overview
Charles Coulomb (June 14, 1736 - August 23, 1806) was a French physicist and military engineer. This lesson will cover his scientific achievements. After the lesson, take the quiz to test your knowledge.
14. Electric Fields: Definition & Examples
Learn what an electric field is, the types of electric fields, and the concept of electric field strength. Briefly investigate specific examples of the types of electric fields.
15. Electric Motor: Definition & Examples
In this lesson, you will learn what an electric motor is, how it works, and some examples of how electric motors are used in everyday life. A short quiz will follow.
16. 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.
17. J.J. Thomson's Cathode Ray Tube (CRT): Definition, Experiment & Diagram
J.J. Thomson's cathode ray tube experiments led to a very important scientific discovery, the electron. In this lesson learn what a cathode ray tube is, and how J.J. Thomson made his discovery.
18. Ohm: Definition & Formula
All electrical circuits have resistance, and the basic unit of resistance is the ohm. This lesson provides a deeper understanding of the ohm, how to calculate resistance in ohms, and a quiz to test your understanding.
19. Parallel Circuits: Definition & Examples
In this lesson, learn more about parallel electrical circuits. We'll review some electrical circuit fundamentals, look at the defining characteristics of parallel circuits, and explore several concrete examples.
20. Positive Charge: Definition & Overview
Positive charges cause your hair to stand up on a cold day and can give you a shock when you touch a doorknob, but they also are responsible for holding atoms together. In this lesson, we'll learn what creates a positive charge and how it interacts with negative charges.
21. What is a Series Circuit? - Definition & Example
In this lesson, we'll define what a series circuit is and compare it with a parallel circuit. Keep reading to see practical examples of series circuits, see descriptions of the components used, and get explanations of the concept of equivalent circuits.
22. What is an Ammeter? - Definition & Function
In this lesson, we'll learn what an ammeter is and what it has to do with electric circuits. We'll also talk about the proper ways to connect an ammeter in series and parallel circuits.
23. What Is Electric Potential? - Definition & Formula
In this lesson, discover what electric potential is and how we measure it. Learn about the scientist Alessandro Volta and why his work led us to name a unit of measurement after him.
24. What Is Electricity? - Definition & Concept
Learn the history of electricity, from Ben Franklin's kite experiment to laptop batteries. Explore the many different ways electricity is measured, generated, and stored.
25. What is Electrolysis? - Definition, Process & Facts
Did you know electrolysis is able to facilitate the decomposition of substances? In this lesson, you'll learn more about the process of electrolysis, after which, you can test your own expertise on the subject with a short quiz.
26. 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.
