AC GENERATION ANALYSISBasic AC TheoryFigure 4 Effective Value of CurrentAnother useful value is the average value of the amplitude during the positive half of the cycle.Equation (7-7) is the mathematical relationship between Iav , Imax , and I.(7-7)Iav0.637 Imax0.90 IEquation (7-8) is the mathematical relationship between Eav , Emax , and E.(7-8)Eav0.637 Emax0.90 EExample 1: The peak value of voltage in an AC circuit is 200 V. What is the RMS value ofthe voltage?E = 0.707 EmaxE = 0.707 (200 V)E = 141.4 VES-07 Page 6 Rev. 0
