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.

Voltage Sources: Energy Conversion and Examples

2. 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.

Electric Potential Energy: Definition & Formula

3. Electric Potential Energy: Definition & Formula

After watching this video, you will be able to explain what electric potential energy is and use an equation to solve electric potential energy problems involving point charges. A short quiz will follow.

Electric Potential: Charge Collections and Volt Unit

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.

Finding the Electric Potential Difference Between Two Points

5. Finding the Electric Potential Difference Between Two Points

After watching this video, you will be able to explain what electric potential difference is and calculate the electric potential difference between two points in a uniform electric field. A short quiz will follow.

Capacitance: Units & Formula

6. 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.

Fixed & Variable Capacitors: Parts & Types

7. Fixed & Variable Capacitors: Parts & Types

Capacitors are devices that store electrical energy. In this lesson, we will explore the various types of capacitors, how they work, and how to calculate equivalent capacitance.

Capacitors: Construction, Charging & Discharging

8. Capacitors: Construction, Charging & Discharging

Electrical circuits have several components, each of which must be understood for the system to work. We're going to check out capacitors in this lesson and see how they can be used to control an electric current.

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

9. 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.

Properties of Transistors, Diodes & Semiconductors

10. Properties of Transistors, Diodes & Semiconductors

When operating with an electronic system, it's important to understand how to control the flow of electricity. In this lesson, we'll look at two semiconductors, transistors and diodes, and see how they help us manage an electrical current.
