电容和电感是电工学中两个重要的物理量,电容器和电感器又是常用的储能元件,从微电子领域到大型电工线路控制都要用到它。但在高中物理课本中出现电容、电感的知识,只是让学生了解浅显的知识,电容和电感在交流电路中的特征学生难于理解。为了使学生对电容、电感知 Capacitors and inductors are two important physical quantities in electrotechnics. Capacitors and inductors are commonly used energy storage devices. They are used in the field of microelectronics to large-scale electrical circuit control. However, the knowledge of capacitance and inductance in high school physics textbooks only allows students to understand superficial knowledge. The characteristics of capacitors and inductors in AC circuits are difficult for students to understand. In order to make students aware of capacitance and electrophysiology
