hat the effects ofwire resistance and of imperfect insulation between line wires areignored in this discussion. When a periodic electromotive force acts across the end of theline, for example when an alternator is connected to the line,then what is called a wave-train passes out along the line, and… … Fig. 144. harmonic alternating voltage, and the curve WW is a curve ofsines. The short horizontal arrows represent the current at variousplaces in the wires, the fine vertical lines represent the lines offorce of the electric field, and the dots represent the lines offorce of the magnetic field as…
