摘要: 研究了3×n阶电阻网络的等效电阻,应用矩阵变换方法求解了差分方程组,给出了3×n阶电阻网络等效电阻的一个简洁的普适规律,并计算出了无穷3×n阶电阻网络的等效电阻,发现无穷3×n阶电阻网络的等效电阻,是一个无理数.

关键词: 3×n阶网络, 差分方程模型, 矩阵变换, 等效电阻

Abstract: The basic structure of a 3 × n -network is studied and the equivalent resistance of the network is calculated. A set of differential equations is solved by using the matrix transform method and thus a general formula for the inlet resistance of 3 ×n -network is proposed. It is found the equivalent resistance of infinity resistance network is an irrational number.

Key words: 3 × n step network, differential equation, matrix transform, equivalent resistance
