1 over square root of 2 or 1/sqrt(2) = 0.70710678118655. This is the effective level of voltage or DC equivalent level of voltage for AC, the alternating voltage supply, which generates the same amount of power as DC. It is calculated using the ROOT MEAN SQUARED method using calculus over a period of 60 hertz … Read more
