1.7.6 Combination of Resistances

Оглавление

In practice, the resistance of a ground path may be due in part to several components. If these are effectively in series (Figure 1.4), the effect is to add the resistance of all component contributors R1…Rn to get a total resistance Rtot.


If resistance of ground paths is in parallel (Figure 1.5), they are combined as
