闭合电路动态分析是高中物理学习中一种常见题型,也是高考的热点之一.如何让学生快速掌握这一解题方法呢?以下我给大家介绍以下具体的解题思路一、先判断总电阻和总电流如何变化一般来讲,从阻值的变化入手,由串并联规律判断出总阻值R总变化情况,根据闭合电路欧姆定律确定电路的总电流如何变化,路端电压如何变化,最后由部分电路欧姆定律及串联分压,并联分流等规律判断个部分的变化情况.
Closed circuit dynamic analysis is a common high school physics learning problems, but also one of the hot spots in college entrance examination.How to let students quickly master this problem-solving method? I will introduce you to the following specific problem-solving ideas First determine the total How the resistance and the total current change In general, starting from the change of the resistance, the total resistance R is determined by the series-parallel connection law. According to the Ohm’s law of the closed circuit, it is determined how the total current of the circuit changes, Finally, some of the circuit Ohm’s law and series partial pressure, parallel shunt and other laws to determine the changes in the part.
