About This Chapter
Georgia Milestones - Physical Science EOC: Electricity- Chapter Summary
The lessons in this chapter of the study guide cover important information you need to know about electricity. In order to pass the Georgia Milestones Physical Science EOC exam, you will need to be comfortable with the fundamentals of electricity and voltage. By the end of this chapter, you should be familiar with:
- Electric current
- Electrical force and charge
- Electric field
- Electric potential
- Sources of voltage
- Insulators vs. conductors
- Electrical resistance
- Fundamentals of electric circuitry
- Resistor-Capacitor (RC) circuits
- Ohm's law
Short and engaging video lessons in this chapter will walk you through each concept in a way that is thorough yet easy for you to understand. The lessons quizzes are there to help you check how much knowledge you have on the topics after completing the lessons. The resources in this chapter are mobile friendly. You can access them whenever or wherever you want as long as you have a reliable Internet connection.
1. 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.
2. 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!
3. Electric Field & the Movement of Charge
After watching this video, you will be able to explain what an electric field is, draw electric field lines and vectors for charged particles, and complete calculations involving electric fields. A short quiz will follow.
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.
5. 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.
6. 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.
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.
8. 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.
9. 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.
10. 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.
