中学物理中常见的电子元件有电阻、电容、电感、二极管,由于这些电子元件有不同的特性也就有着不同的用途.考查学生对电子元件特性掌握情况的试题越来越受命题专家的重视,因此高考复习必须加强电子元件相关试题的讲练.下面对中学物理中关于电子元件的试题进行归类解析,以供参考.第1类:电阻电容组合类电容器有如下特性:(1)电路稳定后,电容器是断路的,同它串联的电阻均可视为短路,电容器两端的电压等于同它并联电路两端的电压;(2)在电路还没有达到稳定以前,与电容器串联的电路中存在充电或放电电流;(3)电容器具有“隔直流通交流,通高频,阻
Secondary physics common in electronic components are resistors, capacitors, inductors, diodes, due to the different characteristics of these electronic components also have different purposes.Examination of students to grasp the characteristics of electronic components more and more subjects by the proposition experts attention, Therefore, entrance exam review must strengthen the teaching of electronic components related questions. The following physics analysis of electronic components on the subject classification analysis, for reference .Class 1: resistor and capacitor combination class capacitors have the following characteristics: (1) circuit Stable, the capacitor is open circuit, with its resistance in series can be regarded as a short circuit, the voltage across the capacitor is equal to the voltage across the parallel circuit with it; (2) in the circuit has not yet reached a stable before the circuit with the capacitor exists Charging or discharging current; (3) Capacitor has ”DC blocking communication, high frequency, resistance
