### 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.

### 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.

### 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.

### 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. 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.

### 6. What is Capacitance? - Definition, Equation & Examples

Capacitors are used to store and quickly release large amounts of electrical energy. In this lesson, we will learn how capacitors are created and used and how your body can function as a capacitor.

### 7. 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.

### 8. 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.

### 9. 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.

### 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.

### 11. The Potential of a Sphere

After watching this lesson, you will be able to explain what electric potential is, state and use the equation for the potential of a sphere, and plot a graph of electric potential with radius. A short quiz will follow.

### 12. The Potential of a Cylinder

After watching this video, you will be able to explain what electric potential is and solve problems using an expression for the electric potential of a cylinder. In AP Physics C, you should be able to derive the expression. A short quiz will follow.
