课程名称：物理忍者：交流电路 课程概述：欢迎参加我的交流电路课程。本课程涵盖了典型的本科基础物理课程中的大部分内容。您将学习如何分析交流电路。课程开始时，我们将从简单的交流电路出发，涉及一个发电机和一个电气元件。您将学会如何用幅度、频率和相位来描述交流信号。同时，您还将学习如何计算电压和电流的均方根值，并理解它们与峰值之间的关系。接下来，我们将解决更复杂的电路，涉及多个电气元件。您将学习如何将基尔霍夫定律应用于交流电路，计算电容和电感的反应，以及使用相量图等特殊技术来求解交流电路中的电流幅值和相位。此外，我们还将讨论交流电路中的能量和功率，学习如何计算发电机提供的功率、阻抗元件上耗散的功率，以及电感器和电容器中储存的能量。课程还将包括关于基本升压和降压变压器的内容，以及如何计算变压器初级和次级侧的电压和电流。课程提供了超过80个解决问题的实例，帮助您掌握这一主题。
Welcome to my course on AC circuits. This course covers most of the material typically covered in a introductory physics undergraduate course. In this course you will learn how to analyze AC circuits. The course starts with simple AC circuits with a generator and a single electrical component. You will learn how to describe an AC signal in terms of an amplitude, frequency, and phase. You will also learn how to calculate RMS values of voltage and current and how they are related to peak values. After, more complex circuits are solved with several electrical components. You will learn how to apply Kirchhoff's laws to AC circuits, how to calculate capacitive and inductive reactance, and use special techniques such as Phasor diagrams, to find the current amplitude and phase in an AC circuit. We will also cover energy and power in AC circuits. You will learn how to calculate the power supplied by the generator, power dissipated by resistors, energy stored in inductors and capacitors. You will also learn about basic step-up and step-down transformers and how to calculate the voltages and currents on the primary and secondary sides of a transformer. This course has over 80 solved problems that will help you master the topic.
