second. When a circuit divides into several parallel branches, eachpossessing resistance and reactance, it is evident that theremight be substituted for the multiple impedances etc., an equivalent impedance ^B^ + (Lm j > without change of the main current, either in magnitude or phase.

The first has a net inductive reactance = L^a>,the second a net capacity reactance = — > and the third anet inductive reactance = igw. We then have the impressed IMPEDANCE 83 electro-motive force…
