一个较复杂的电阻电路往往不能用简单的串、并联来计算,因为包含了一个称作△(或π形)形的三角再网络,若由△转换到Y(图1),再计算就方便多了.但由△转换到Y的计算过程十分繁复.本诺模图就是为了这一转换而设计的.被用作作图根据 A more complicated resistor circuit can not usually be calculated in simple strings and in parallel because it contains a triangular re-network called the delta (or pi) shape, which is easily recalculated if it is converted from Δ to Y (Figure 1) However, the calculation process from △ to Y is very complicated. The Benotem model is designed for this conversion and is used as a basis for mapping
