摘要: 利用Y→△电导等效转换公式,将各边电阻皆相等的n级三角梯形电阻网络简化为1级三角形电阻网络,其腰边电阻为nr,底边电阻递推通式为Rn=αQn-1(m-β)-βP^n-1(m-α)^-Q^n-1(m-β)-P^n-1(m-α)。

关键词: 三角梯形电阻网络, Y→△转换, 腰边电阻, 底边电阻

Abstract: By using the Y→△ conductance equivalent transformation formula, we simplify the regularly-connected n-level triangle ladder resistor network with the same resistance in each branch circuit into the one-level triangle resistor network. Whose waist edge resistance is nr and whose recursion formula for the bottom edge resistance is Rn=αQn-1(m-β)-βP^n-1(m-α)^-Q^n-1(m-β)-P^n-1(m-α).

Key words: triangle ladder resistance networks, star-triangle equivalent transformation, waist edge resistance, bottom edge resistance
