Another 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.
Equation (7-8) is the mathematical relationship between Eav , Emax , and E.
The peak value of voltage in an AC circuit is 200 V. What is the RMS value of
E = 0.707 Emax
E = 0.707 (200 V)
E = 141.4 V
