Objectives of the HiSET Science: Electricity & Magnetism Chapter

The HiSET Science subtest is one of the five HiSET subtests examinees must pass to earn a high school equivalency credential. This subtest is concerned with not just what you know but also how well you can apply your subject knowledge. On the subtest you'll see multiple science areas covered in the questions, including information you'll get familiar with in this chapter. The items that deal with this chapter will be part of the 50 multiple-choice questions on the subtest. The practice quizzes you find in the Electricity & Magnetism chapter also are in multiple-choice format and give you helpful visuals to study the parallel HiSET Science items.

18 Lessons in Chapter 22: HiSET: Electricity & Magnetism
Electric Charge and Force: Definition, Repulsion & Attraction

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!

Electric Force Fields and the Significance of Arrow Direction & Spacing

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.

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

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.

Electric Potential: Charge Collections and Volt Unit

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.

Insulators and Conductors: Examples, Definitions & Qualities

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.

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.

Electric Circuit Fundamentals: Components & Types

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.

What is Electric Power?

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.

Magnetic Force: Definition, Poles & Dipoles

12. 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.

What is a Magnetic Field?

13. 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.

How Magnetic Fields Are Created

14. 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.

How Magnetic Forces Affect Moving Charges

15. 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.

Electromagnetic Induction: Definition & Variables that Affect Induction

16. 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

17. 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.

Electric Motors & Generators: Converting Between Electrical and Mechanical Energy

18. Electric Motors & Generators: Converting Between Electrical and Mechanical Energy

Both generators and electric motors are common devices in everyday life, but how do they work and what is the difference between them? In this lesson, we'll explore both of them, which may produce different results but are actually more similar than they may seem.
