从一道电路题探析解法的多样性

Study on Multi Solutions of a Circuit Problem

电路模型的简便求解是电路分析的目的.通过对一道电路题的解法探究了电路分析解题方法的多样性,共计给出了8种解法,每种方法都有一定的代表性但并不是唯一的,其中第4种和第6种解法技巧性较强,而第7种和第8种解法具有计算机软件解题的普遍性,这些解题方法代表的解题思想具有一定的借鉴意义,若能融会贯通则对电路分析的简便进行有很大的帮助.

The purpose of the circuit analysis is to seek a simple solution of circuit model. The diversity of solution method was studied by solving a specific circuit problem. Eight solutions were provided and each one was representation but not unique. The fourth and sixth solutions demand strong skills. The seventh and eighth solutions have considerable universality by computer soft- ware. The thought of solving the problem has certain reference significance for circuit analysis. It may help students to grasp the learning to achieve mastery through a comprehensive study of circuit analysis. So it is helpful to seek a simple and convenient solution.
