About This Chapter
Capacitors, Inductors & Alternating Current - Chapter Summary
Fun lessons in this entertaining chapter can ensure you have a quality understanding of capacitors, inductors and alternating current. No matter your current knowledge level, our instructors can help you gain full comprehension of R-L-C series circuits, series capacitors and more. To get started, select any lesson as your first, review its contents and feel free to take its accompanying quiz to test your comprehension. Progress through the chapter by selecting more lessons, taking additional quizzes and finishing with our practice exam. If you develop lesson topic questions while studying, be sure to submit them to our experts. When finished, you will be ready to do the following:
- Define impedance in alternating current circuits
- Explain the meaning of an R-L-C series circuit and solve related problems
- Make alternating current power calculations
- Describe the construction of capacitors
- Compare and contrast series and parallel capacitors
- Solve practice problems involving resistor-capacitor (RC) circuits
1. 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.
2. Series & Parallel Capacitors
A capacitor is used to store electrical energy in a circuit. In this lesson, learn how to calculate the equivalent capacitance of circuits containing series and parallel capacitors.
3. Resistor-Capacitor (RC) Circuits: Practice Problems
After watching this video, you will be able to calculate or deduce the current and voltage in the components of an RC circuit at the start of the charging process and when the capacitor is fully charged. A short quiz will follow.
4. R-L-C Series Circuits
After watching this lesson, you will be able to explain what an RLC series circuit is and use related equations to solve simple problems. A short quiz will follow.
5. Alternating Current Power Calculations
After watching this lesson, you will be able to explain the difference between AC and DC circuits and calculate AC current, AC voltage and AC power using both rms values and peak values. A short quiz will follow.
6. Impedance in Alternating Current Circuits
In this lesson, you will learn about topics that include the difference between DC and AC circuits, the use of rms values, definitions of impedance and reactance, and calculations involving the reactance of capacitors and inductors.
