**IGCSE 物理课程：第三章 电学（第一部分：基础电学）摘要** 本课程是剑桥 CIE IGCSE 物理（0625）拓展课程的第三章“电学”系列的第一部分，专注于“基础电学”。课程内容完全遵循考试大纲，时长约 1 小时 43 分钟，每个视频平均时长 3 分钟，旨在高效精准地传授知识，避免时间浪费。 本课程涵盖了基础电学的所有理论知识点，旨在帮助学生掌握回答 Paper 1（选择题）、Paper 3（结构题）和 Paper 6（实践替代题）相关试题的基础。 **课程大纲：** * **第一课：磁学 (Magnetism)** * 条形磁铁 * 磁场 * 磁化与退磁方法 * **第二课：静电学 (Electrostatics)** * 带电体 * 充电方法 * 电场 * 静电力 * **第三课：电流 (Electric current)** * **方程与理论：** * 与电流和电路相关的方程 * 电压、电流强度和电阻的概念 * 欧姆定律及其证明 * 可变电阻器 (Variable resistor) * 电位器 (Potentiometer) * 电路符号 * **第四课：家庭电路安装 (Home Installation)** * 电力如何进入家庭 * 用电危险源 * 安全注意事项 本课程为后续的“电磁学”和“电子学”部分奠定坚实的理论基础。
*This Course is about Extended Cambridge (0625) IGCSE Physics… Chapter 3: Electricity, * This chapter is divided into three courses Part1: Basic Electricity, Part 2: Electromagnetism, Part 3: Electronics, This course is only part 1 Basic Electricity, other parts will be in other courses, *This course covers all the points in the syllabus that are related to Electricity (Part1), *The course is directed to the point and restricted to the syllabus nothing less and nothing more, so you will not waste your time, with invaluable speech, * If you know exactly your syllabus you will appreciate these videos, * The average video duration is 3 mins so you will not get bored with the course and you can find reasonable points to pause and complete later, * The full course duration is about 1 hours and 43 mins * This course includes four lessons: Lesson 1: Magnetism, Lesson 2: Electrostatics, Lesson 3: Electric current (Equations and Theoriticls) Lesson 4: Home Installation, This course is arranged so that it covers all points about basic electricity, This course mainly covers the theoretical parts that puts the basics that will help you answer all past paper questions related to Basic Electricity in paper 1 ( the multiple choice), paper 3 (structured questions), and paper 6 ( the alternative to practical), Lesson 1 Magnetism, this includes bar magnets, magnetic fields, magnetization and demagnetization methods, Lesson 2 Electrostatics, includes charged bodies, methods of charging, electric field and electric forces Lesson 3 Electric current is separated into two parts, the first part is the equations, this includes all the equations related to electric current and electric circuits, also explaining the concepts of voltage, current intensity and electric resistance, after that comes the theoretical part which includes definitions, proving ohm's law, the variable resistor, the potentiometer, and electric symbols, Lesson 4 Home installation, how electricity reaches our homes, some sources of dangers and safety precautions,
