(a) The emf produced by a typical hydroelectric generator, at thegenerator, is 20,000 V. The electricity produced by the generator is fedthrough a step-up transformer before being transmitted across thecountry on "high tension" lines like those shown in the textbook. If theprimary winding of the transformer has 1550 loops, what must be themultiplicity of the secondary winding to produce a transmission emf of100,000 V? Of 225,000 V? Of 345,000 V? (b) A current of 4500 A flowsfrom the generator to the step-up transformer. What current flowsthrough the transmission lines at each one of the three operating emfsstated in part a?
