闭合电路动态分析题一直是高中物理闭合电路部分的一个难点,尤其是一些复杂的电路,常常令许多同学感到无从下手.笔者经过认真分析,总结出一种简单快速的解题方法,即电压与电流根据电阻的变化重新分配的规律,笔者命名为“分压定理”.此法在教学实施中效果显著.下面向大家介绍“分压定理”及其应用. Closed circuit dynamic analysis of the problem has been a high school physical closed circuit part of a difficulty, especially some complex circuits, many students often feel startled.The author after careful analysis, summed up a simple and quick method of solving problems, that is, voltage and The current redistribution according to the change of resistance law, the author named “partial pressure theorem ” .This method in teaching implementation effect is remarkable .Introduction to the following “partial pressure theorem ” and its application.
