for impedance as given in equation (1),page 1.058, must be modified to include the reactance due tocapacity, because, as explained, inductive and capacity reactanceswork in opposition to each other, in the sense that the react-ance of inductance acts in direct proportion to the quantity2t/L, and… … •:.rr;vE coil ALTERNA-CR PlC 1,300.—Diagram of circuit for example IV. 72.4 0MM5 To properly estimate impedance then, in such circuits, thefollowing equation is used: impedance = V resistance -+- (inductance reactance — capacity reactance)* or using symbols, Z = > k: - X,- (3) EXAMPLE IV.—A…
