TExES Physical Science 6-12: Electricity & Magnetism - Chapter Summary
In this TEXES Physical Science 6-12 chapter, you'll find short video lessons on magnetism and electricity. Concepts outlined here include magnetic force and how it affects moving charges. You'll also review the definition of a magnetic field and how they are created. Once you finish these lessons, you should be ready to achieve the following objectives:
- Outline the variables that affect electromagnetic induction
- Discuss conductor to conductor induction and transformers
- Define electric current and list its uses
- Detail the variables and units of electrical resistance
- Identify the components of electric circuits
- Apply Kirchhoff's rules
- Explain how resistor-capacitor (RC) circuits work
Even the most challenging topics are easy to understand when you have our expertly taught videos to watch. If you have any questions as you progress through the chapter, reach out to one of our experts through the Dashboard. The lesson quizzes and chapter test can give you a sense for how ready you are to take the exam and any areas that need more work.
1. 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.
2. How Magnetic Forces Affect Moving Charges
A magnetic field exerts a force on a moving charged particle in ways that you might not expect. In this lesson, we're going to look at the direction of this force and the factors that affect its strength.
3. 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.
4. How Magnetic Fields Are Created
Have you ever wondered how magnetic fields are created? In this lesson, we'll discuss the very simple answer to this question and look at how electric current can be used to make electromagnets, which have many everyday applications.
5. 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.
6. Electromagnetic Induction: Conductor to Conductor & Transformers
Every day, we make use of a special case of electromagnetic induction known as mutual induction. In this lesson, we'll talk about this special phenomenon and how it is used in many common devices.
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. 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.
10. Applying Kirchhoff's Rules: Examples & Problems
Ohm's Law can be useful for analyzing simple circuits, but when circuits are more complex, as they often are, we can instead analyze the circuits using Kirchhoff's rules. Learn about Kirchhoff's rules in this lesson.
11. Resistor-Capacitor (RC) Circuits: Definition & Explanation
Resistor-capacitor (RC) circuits are everywhere because they are useful in our everyday lives. The current in these circuits varies with time, making them both practical and common in many types of electronic equipment.
