How to calculate the .707 value used in rms voltage

  1. Nov 16, 2011 #1
    I need help, and cant find anywhere how to calculate the .707 value using calculus. The value used when calculating Vrms =Vp*.707, i need to know how to calculate the .707. Any help would be great, Thanks!

    .707 is for a sine wave only, and you could determine it by taking the integral of V(t)2 over a full cycle, dividing by the time of the cycle, and then taking the square root of the answer (hence the name "root mean square").
