Fig. 1,221.—Diagram showing one alternation of the current in which the latter varies from zeroto maximum and back to zero while the generating loop ABCD makes one half revolution. Ques. What is the amplitude of the current? Ans. The greatest value of the current strength attainedduring the cycle.… … Fig. 1,222.—Diagram illustrating amplitude of the current. The current reaches its amplitudeor maximum value in one quarter period from its point of zero value, as, for instance, whilethe generating loop moves from position ABCD to ABCD. At three-quarter revo-lution, the current reaches its maximum…
