In other words, the drop of potential in aninductive line is greater if the receiving circuit is inductive thanif it is non-inductive. From Fig. 16, Ea = V(E cos e + /r)2 + {E sin 6 + Ixy~.If, however, the current in the receiving circuit is leading, as 26 ALTERNATING-CURRENT PHENOMENA is the case when feeding condensers or synchronous motors whosecounter is larger than the impressed voltage, then thevoltage will , in Fig. 17, by a vector, OE, laggingbehind the current, 01, by the angle of lead,
