Not illustrated. 1902 Excerpt: ...of Flow.--It is well known that the character of the tidal flow is greatly affected by the character of the channel. For instance, in a narrow, crooked channel the phase of the flow is retarded as one proceeds along its length, through the buffeting action of the banks; and the times of high and low tides, when the flow in the channel is zero, may not correspond with the times of similar tidal phases in some other channel or in the open sea. In this case we may say that the tide in one channel Differs in Phase from that in the other or that in the sea; and a chart may be drawn to represent the respective cycles of sea and channel tides at certain selected points, as in Figure 150. In this figure the tidal cycle in the channel is shown to be Retarded, or behind the tidal cycle of the sea. Alternating currents of electricity, flowing in branch circuits, may be at different phases, and they may be represented on a chart entirely similar to that of Figure 150. The currents are said to be Out of Phase, and may be said to be in advance of or behind each other, depending upon which is looked upon as the datum for comparison, --exactly, for instance, as we may with equal propriety and the same meaning say either that the channel tide is behind the tide of the open sea, or that the tide of the open sea is in advance of the channel tide. 221. Summing Up.--To recapitulate, the electric current may be Continuous, Pulsating, or Alternating. The first is likened toacontinuous flow of a river; the second, to the pulsating flow of arterial blood; and the third, to the alternating flow of water in a tideway. Continuous and pulsating currents, that is, currents which flow continuously in one direction, are called Direct Currents. FlG. 150.--Graphical Record of Two Alternating..
