TExES Science 7-12: Electricity and Magnetism - Chapter Summary

This chapter helps you study for the TExES Science 7-12 exam with lessons covering electricity and magnetism, including thorough explanations of the ways magnetic forces affect moving charges, poles and dipoles, electromagnetic induction and series circuits. Additionally, by the end of this chapter, you should be familiar with:

  • Explaining the variables that affect electromagnetic induction
  • Detailing electromagnetic induction
  • Defining electrical current and resistance
  • Applying Kirchhoff's rules
  • Summarizing resister-capacitor circuits
  • Identifying the seven major regions of the electromagnetic spectrum
  • Finding the equivalent resistance of parallel and combination circuits

The short, engaging video lessons walk you through each topic and make studying electricity and magnetism fun. The jump feature in the timeline allows you to skip directly to main topics within the video, so you can rewatch just those areas you need to re-review. End each lesson with a self-assessment quiz to make sure you understand what you've studied.

The 7 Major Regions of the Electromagnetic Spectrum

1. The 7 Major Regions of the Electromagnetic Spectrum

This lesson will walk you through each of the major regions of the electromagnetic spectrum. Explore the unique characteristics of X-rays, microwaves, radio waves, UV rays, infrared, gamma rays, and of course, visible light.

How Magnetic Forces Affect Moving Charges

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.

Magnetic Force: Definition, Poles & Dipoles

3. 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.

Electromagnetic Induction: Definition & Variables that Affect Induction

4. 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.

Electromagnetic Induction: Conductor to Conductor & Transformers

5. 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.

What is Electric Current? - Definition, Unit & Types

6. 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

7. 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.

Finding the Equivalent Resistance: Series, Parallel & Combination Circuits

8. Finding the Equivalent Resistance: Series, Parallel & Combination Circuits

How does resistance impact the way that electrical currents flow through a circuit That's what we are exploring in this lesson. We'll check out resistance in the three main kinds of circuits and practice calculating this value.

Applying Kirchhoff's Rules: Examples & Problems

9. 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.

Resistor-Capacitor (RC) Circuits: Definition & Explanation

10. 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.
