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. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. What is a Magnet? - Definition & Examples
In this lesson, you will learn what a magnet is and how it works at the atomic level. You'll also see how the earth's magnetic field works. A short quiz will follow.
8. 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.
9. What is an Electromagnet? - Definition, Uses & Parts
In this lesson, you'll learn what an electromagnet is, how it is used in a few real-life situations, and the parts that make it up. A short quiz will follow.
10. Permanent Magnets: Characteristics & Strength
Permanent magnets generate their own magnetic fields. In this lesson, we will discuss the characteristics of permanent magnets, and what affects how strong they are.
