课程名称：交流电路与应用数学 课程概述：本课程涵盖了交流电（AC）电力的所有方面，并结合了相关的应用数学理论。课程从交流电的生成开始，深入探讨了交流正弦波，并讲解了峰值、峰到峰值、平均值和有效值（RMS）的概念。课程中定义了交流发电机的所有组件，包括交流电的产生方式和如何通过刷子与滑环从发电机中提取交流电。学员将学习电感器（线圈）、电容器、电磁铁和变压器的工作原理，以及它们在串联和并联配置中的表现。课程详细讲解了功率因素及其修正，涵盖了电容性反应、感应性反应和LCR电路，使用了应用数学来描述这些概念。学员将理解到，在直流电路中组件的行为与在交流电路中的反应是截然不同的。与直流电路中使用的电阻欧姆不同，交流电路中将使用反应欧姆来描述对电流流动的阻抗。课程中的关键词包括：电感、 电容、电容性反应、感应性反应、阻抗、功率因素、功率因素修正、正弦波形和共振。此外，还讨论了变压器的类型，如升压变压器、降压变压器、单相、三相、比率和比例、自耦变压器以及配电变压器。 此课程旨在帮助学员全面理解交流电的基础知识及其应用，适合对电气工程和物理感兴趣的学习者。
This course covers all aspects of alternating current (AC) electricity and includes the associated theory with applied math. It begins with how AC is generated and takes a thorough look at the AC sine wave and how we arrive at peak values, peak to peak values, average values, and effective or RMS values. All components of an AC generator are defined from how the AC is produced to how it is extracted from the generator using brushes and slip rings. Inductors (coils), capacitors, solenoids, and transformers are defined and described, and the student will have a good understanding how they work in series and parallel configurations. Power factor is defined and described in detail along with power factor correction. Capacitive reactance, Inductive reactance, and LCR circuits are described using all of the applied mathematics. Students will understand that how components behave in a DC circuit is quite different than how components react in an AC circuit. Unlike ohms of resistance that are used in DC circuits, ohms of reactance will be used to describe opposition to current flow. Key terms are: inductance, capacitance, capacitive reactance, inductive reactance, impedance, power factor, power factor correction, sinusoidal wave forms, and resonance. Transformer type are discussed such as step up, step down, single phase, three phase, ratios and proportions, auto transformers, and distribution transformers.
