. Hawkins electrical guide. Questions, answers & illustrations; a progressive course of study for engineers, electricians, students and those desiring to acquire a working knowledge of electricity and its applications; a practical treatise. e changes comprise the cycle which is repeatedwith great rapidity. The properties of alternating currents are more complex than thoseof continuous currents, and their behavior more difficult to arises from the fact that the magnetic effects are of far moreimportance than those of steady currents. With the latter the mag-netic effect is constant, and has no reactive influence on the currentwhen the latter is once established. The lines of force, however, producedby alternating currents are changing as rapidly as the current itself,and they thus induce electric pressures in neighboring circuits, andeven in adjacent parts of the same circuit. This inductive influence inalternating currents renders their action very different from that ofcontinuous current. Ques. What are the advantages of alternating currentover direct current? Ans. The reduced cost of transmission by use of high voltagesand transformers, greater simplicity of generators and motors, 098 ELECTRICITYhawkinselectrica05hawk. 12
