**课程名称：** 电子学 S1W7：电阻并联 **课程概述：** 本课程将系统地学习并应用并联电阻电路的原理、定律和公式，以解决相关问题。课程结束后，学员将能够： * 解释为何并联电阻电路的总电阻总是小于电路中最小的电阻值。 * 学习并演示使用并联电阻公式确定并联电路的总电阻。 * 应用“乘积除以和”的方法精确计算两个并联电阻的总电阻。 * 学习并应用基尔霍夫电流定律和电流分配公式，确定并联电路中不同支路的电流。 * 掌握正确使用“||”符号来书写任意并联电阻电路的公式。 * 陈述并应用能够计算任意多个相同阻值电阻的总电阻的公式。 * 利用所学规则和公式解决七个由讲师提供的并联电阻问题，并学习每个问题的详细解决方案。 * 计算电路的总功率以及每个元件的个别功率。 **内容回顾：** 本课程最后将对所有已学的串联和并联电阻公式及定律进行全面复习。 **前提知识：** 本课程需要学员具备串联电阻电路的相关知识，这些知识已在先修课程“电子学 S1W5：电阻串联”中涵盖。未完成该课程的学员应熟悉欧姆定律和基尔霍夫电压定律，以便能够解决串联电阻电路。 **课程构成：** 本课程共包含十四个视频，总时长约为 2.5 小时。大多数视频时长在 8 至 13 分钟之间，每个视频教授课程概述中一个或多个概念。 **适用人群：** 本课程适合有志于从事电子行业、希望成为严肃的电子爱好者，或者仅仅想了解电子学工作原理的学习者。
During this course, the student will learn and apply the principles, laws and formulas that will lead to the solution of problems in parallelresistive circuits. By the end of this course, you will:- Be able to state why the total resistance in any parallel resistance circuit is always smaller than the value of the smallest resistor in the circuit.- Learn and demonstrate the use of the Parallel Resistance Formula to determine the resistance of parallel circuits.- Apply the Product Over the Sum method to accurately determine the total resistance of any two parallel resistors.- Learn and apply Kirchhoff's Current Law and the Current Divider Formula to determine the current flow in different branches of a parallel circuit.- Learn how to correctly use the bar-bar symbol () to correctly write the formula for any parallel resistance circuit.- State and apply the formula that will allow you to determine the total resistance of any number of resistors that have the same value.- Solve seven parallel resistance problems presented by the instructor, using all of the rules and formulas you have learned to this point. The instructor will give you a detailed solution to each of the problems.- Demonstrate that you can compute the total power in a circuit, and the individual power for each component.Summary of Series and Parallel CircuitsThe course concludes with a thorough review of all of the formulas and laws of series and parallel resistance that you have learned so far.This course presumes some knowledge of series resistive problems. These topics were covered in the prerequisite course: "Electronics S1W5:Resistors in Series". If you did not complete this course, you should be familiar with Ohm's Law and Kirchhoff's Voltage Law, so that you can solve series resistive circuits.This course is composed of fourteen videos with a total rumnning time of about 2.5 hours. Most videos run for 8 to 13 minutes, and each teaches one or more of the concepts shown in the bullet points above.If you are headed for a career in electronics, or want to become a serious electronics hobbyist, or just want to know how electronics works, then this is a course for you.
