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
Magnetic fields are generated when charged particles move around. Explore more about magnetic fields, their source, current carrying conductors, and electromagnets and how they act.
2. What is Electric Current? - Definition, Unit & Types
Electrical current involves the flow of charged particles, or electrons, and it is an integral part of electricity. In this lesson, we will dive into the definition of current, as well as the unit and types to understand just how electricity moves.
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
Electric motors are used for converting electrical energy to mechanical energy, while generators are used for converting mechanical energy to electrical energy. Learn about electromagnetic induction, and the role of alternating and direct currents in the conversion.
5. Parallel Circuits: Definition & Concepts
A parallel circuit possesses different branches and paths where the current can flow. Understand the definition of a parallel circuit, and explore relevant concepts such as the pathways and resistance in this type of circuit, as well as Ohm's law.
6. Series Circuits: Definition & Concepts
A series circuit is a circuit that has only one path in which current can flow, going through each component. Learn about circuit pathways and the concept behind a single pathway, explore the definition of a series circuit, and understand the relation of resistance and voltage to the current in a series circuit.
7. What is Electric Power?
Electric power and its ability to measure energy in watts has become something that technical and non-technical people can understand quite easily. This lesson considers electric power, watts, current, voltage, resistance, and all of these variables' relation to each other.
8. Electrical Resistance: Definition, Unit & Variables
Electrical resistance refers to the force that impedes electrons in an electrical current flowing through a conductor. Explore the causes of electrical resistance, the various factors that can affect the resistance of different objects, as well as the practical applications of objects with high resistance.
9. Ohm's Law: Definition & Relationship Between Voltage, Current & Resistance
Ohm's Law describes the relationship between voltage, current, and resistance. Learn about Ohm's Law and understand this relationship, including its importance. Use the Ohm's Law equation to calculate the values of voltage, current, and resistance.
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.
