摘要
利用n阶有限梯形电阻网络等效电阻值与无限梯形电阻网络的等效电阻值差的关系,给出n阶有限梯形电阻网络等效电阻的近似计算公式,数值计算表明所给近似计算公式对于计算有限梯形电阻网络等效电阻精确程度较高.
By analyzing the difference of equivalent resistance value between unlimited ladder-shaped resistance network and n-rank limited ladder-shaped resistance network,an approximate formula was given to calculate the equivalent resistance value of n-rank limited ladder-shaped resistance network,which bears the advantage of having high degree of accuracy to calculate the equivalent resistance value of limited ladder-shaped resistance network through the proof of numerical calculations.
