CSET Science: Electricity and Magnetism - Chapter Summary
The lessons in this chapter can help you develop your knowledge of the relationship between electricity and magnetism in preparation for the California Subject Examinations for Teachers (CSET) Science test. You'll also learn to use this knowledge to understand many applications, such as generators and motors. These video lessons cover topics including:
- Description and examples of electrostatic and magnetostatic phenomena
- Electric charge and force: definition, repulsion and attraction
- Definition, unit and types of electric current
- Magnetic force: definition, poles and dipoles
- Magnetic fields: definition, how they are created and how they affect moving charges
- Relating electric current to magnetic fields and the application of these relationships
- Components and types of electric circuit fundamentals
- Design and interpret simple series and parallel circuits
- Definition and calculating power, voltage differences, current and resistance in simple circuits
With guidance from expert instructors, you'll get a firm foundation in the principles and uses of electricity and magnetism. These engaging video lessons will enable you to understand applications of these forces and prepare for the CSET.
Objectives of the CSET Science: Electricity and Magnetism Chapter
Applicants for some types of California teaching credentials must pass CSET tests. Questions relating to electricity and magnetism are on the General Science: Subtest I. This subtest has 58 multiple-choice questions, and six of those are about electricity and magnetism. You'll be able to check your knowledge of these topics through the self-assessment quizzes at the end of the lessons as well as get a feel for the actual format of the test questions.
1. 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.
2. 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.
3. The Role of Magnetic Force in Technological Devices
After completing this lesson, you will be able to explain what magnetic forces are, and describe various technological devices that use magnets. A short quiz will follow.
4. 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.
5. 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.
6. 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.
7. 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.
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. Energy Transfers in Circuits: Equations & Examples
In a circuit, energy is always being transformed from electrical energy into other forms, like light and thermal energy. In this lesson, learn how energy is transformed and how to calculate exactly how much energy is transformed in a circuit.
