串并联电路特点是初中物理电学部分的重要内容,是学生学好电学的基础。我自己制作的这个串并联电路演示器,利用简单、形象、直观的实验现象,既可以帮助学生深入理解“串联电路各元件相互影响,并联电路各元件相互不影响”这一电路特点,又可以作为地理教具,用绿色发光二极管生动展示中国地形三阶梯示意图。下面就让我来向大家展示一下它的制作过程。一、准备器材发光二极管200多个(红、绿两种颜色),发光二极管座两个,遥控
Serial and parallel circuit characteristics are the important part of the junior middle school physics, which is the basis for students to learn electrical science. The serial parallel circuit demonstrator I made by myself uses a simple, visual, and intuitive experimental phenomenon to help students understand in depth the effects of each component of the series circuit, and the components of the parallel circuit do not affect each other. It can also be used as a geographic teaching aid, with green light-emitting diodes to vividly demonstrate the three-step diagram of China’s terrain. Let me show you the process of making it. First, prepare more than 200 light-emitting diodes (red, green two colors), two LED blocks, remote control
