Re: 問題57:無限に続く抵抗ラダー回路の解析
最初の命題についてはオーソドックスな代入法による方程式の解法を用いれば導き出せた。

In=Inplus1+Idashn
Inplus1=Inplus2+Idashnplus1
Idashn*R=Inplus1*R+Idashnplus1*R+Inplus1*R

1番目の式からIdashnは

Idashn=In-Inplus1

2番目の式からIdashnplus1は

Idashnplus1=Inplus1-Inplus2

上記のIdashnとIdashnplu1で3番目の式を置換すると

(In-Inplus1)*R=Inplus1*R+(Inplus1-Inplus2)*R+Inplus1*R

In*R-Inplus1*R=Inplus1*R+Inplus1*R-Inplus2*R+Inplus1*R

両辺をRで割ると

In-Inplus1=Inplus1+Inplus1-Inplus2+Inplus1

整理すると

In=4*Inplus1-Inplus2

従って

In - 4*Inplus1 + Inplus2 = 0

が成り立つ
