sary in obtaining the impressed pressure sinceit is simply the difference between inductance pressure and capacitypressure (the circuit being assumed to have no resistance), that is impressed pressure = E« — Ec = 377 — 255 = 122 volts. EXAMPLE.—A circuit in which a current of 20 amperes is… … ZERO LINE Fig. 1,335.—Impedance diagram for circuit (of above example) containing inductance andcapacity. With any convenient scale, erect a perpendicular AB = 18.25 ohms, and CD =12.76 ohms. Continue CD by dotted line to D so that CD = AB. then DD =AB - CD= inductance reactance —capacity…
