which we find the current 225 z = </r2 + (2 7r ~ Lf 44). This formula enables us to predetermine the currentwhen the frequency, E.M.F., resistance, and self-induc-tion of the circuit are given. The analogy with Ohmslaw is apparent at a glance. In the formula expressingOhms law the denominator is… … impedance, and may, according to Dr. Fleming, berepresented as the hypothenuse of a right-angular tri-angle, the sides of which represent resistance and in-ductance as shown in Fig. 79. In the above investigation we have arrived at theprinciple according to which the power given to acurrent must be…
