Use this circuit overview chapter to help you get ready for the OAE Physics assessment. The fun lessons in this chapter are designed to give you the insight you need to answer questions on the exam that address the following:
- Defining and analyzing qualities of insulators and conductors
- Examining the definition, unit and types of electric current
- Understanding units of electrical resistance
- Analyzing Ohm's law and the relationship between voltage, current and resistance
- Defining electric power
- Determining how to apply Kirchhoff's Rules
- Explaining resistor-capacitor (RC) circuits
Exploring the videos gives you access to a comprehensive overview of circuits. Instructors offer step-by-step guidance while presenting information in an entertaining manner that makes the studying process fun. In addition to watching engaging video lessons, you can take self-assessment quizzes and a chapter exam to test your comprehension of the materials. If you need to review a specific topic, you can use the timelines to jump to certain portions of the videos.
OAE Physics: Circuit Overview - Chapter Objectives
The OAE Physics assessment is part of the qualification process for teaching licensure in the state of Ohio. To help you prepare for the test, this OAE Physics: Circuit Overview chapter explores topics that are covered in the electricity and magnetism domain of the assessment, which constitutes approximately 22% of the entire test.
The assessment is composed of 150 multiple-choice questions, many of which feature a table, graph, diagram or other illustration to help you conceptualize and answer a question. After reading the question, you will be asked to review four answers, one of which you'll need to select as the best response.
1. 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.
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. 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.
4. 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.
5. 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.
6. 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.
7. 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.
