Electric Field & the Movement of Charge

1. 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.

What is Electric Current? - Definition, Unit & Types

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.

Electrical Resistance: Definition, Unit & Variables

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.

Types & Components of Electric Circuits

4. Types & Components of Electric Circuits

Learn about electrical components and types of circuits. By the end of this lesson, you'll be able to explain what components like bulbs, resistors, and capacitors do. You'll also be able to compare and contrast series vs. parallel circuits and DC vs. AC circuits.

Voltage Sources: Energy Conversion and Examples

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.

Ohm's Law: Definition & Relationship Between Voltage, Current & Resistance

6. 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.

Applying Kirchhoff's Rules: Examples & Problems

7. 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.

Capacitance: Units & Formula

8. Capacitance: Units & Formula

After watching this lesson, you will be able to explain what a capacitor is, define capacitance, and solve simple problems using capacitance equations. A short quiz will follow.

Resistor-Capacitor (RC) Circuits: Definition & Explanation

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.

Magnetic Force: Definition, Poles & Dipoles

10. Magnetic Force: Definition, Poles & Dipoles

You're probably familiar with magnets, but have you ever stopped to consider how they work? In this lesson, we'll look at the root of magnetism and some of the fundamental properties of magnets.

Magnetic Field: Definition & Creation

11. Magnetic Field: Definition & Creation

After completing this lesson, you will be able to explain what a magnetic field is, how they are created, and suggest some uses for magnetic fields. A short quiz will follow.

Force of Attraction: Formula & Concept

12. Force of Attraction: Formula & Concept

In this lesson, you will learn about the force of attraction and the kinds of forces that cause attraction. You will learn the formulas for these forces and learn how to calculate the force of attraction in each case, and learn about the properties of each force of attraction.

Overview of Electromagnetic Induction

13. Overview of Electromagnetic Induction

After completing this lesson, you will be able to explain what electromagnetic induction is and describe how it is used to generate electricity in our everyday lives. A short quiz follows the lesson.
