GACE Physics: Electric Circuits - Chapter Summary
If you'd like to brush up on electric circuits before your GACE Physics assessment, then you're in the right place. By refreshing your memory on such subject matter, this chapter's effective resources will have you ready for any questions on the following:
- Qualities of insulators and conductors
- Variables of electrical resistance
- Ohm's law and Kirchhoff's rules
- Resister-capacitor (RC) circuits
Explore these video lessons from your computer or mobile device. The video tags allow you to easily track down any portions of the lessons that you'd like to reexamine after taking the quizzes.
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.
