About This Chapter
Electric Potential and Capacitance - Chapter Summary
Use the lessons found in this chapter as part of your review of what you studied in college about electric potential and capacitance. The videos go over electric force and electric field, electric potential energy, and electric potential difference. These lessons will also address the following topics:
- Batteries and conversion of energy
- Charge collections and volt units
- Principle parts and construction of a capacitor
- Voltage, current and resistance and Ohm's Law
- Transistors, diodes and semiconductors
Our instructors go over each point, highlighting the important aspects. By using multiple didactic strategies, learning the key points becomes easier, and retention is improved.
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. 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.
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.
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.
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.
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.
