Homework Help: Greatest RMS voltage generated in a circuluar loop antenna

  1. Nov 25, 2007 #1
    1. The problem statement, all variables and given/known data[/
    What is the greatest RMS voltage generated in a circuluar loop antenna which is 30.0 cm in radius (also located 14.0 km away)

    2. Relevant equations
    [tex] V=wA [/tex]


    3. The attempt at a solution
    So the frequency is 170MHz.
    My question is how to deal with the root mean squared.
    is it:
    [tex] V=\frac{wA}{\sqrt 2}[/tex]? A is area by the way

    do i perform [tex] V=\frac{wA}{\sqrt 2}[/tex]
    or do i need to intergrate since this is a continious distribution?
    [tex] V_rms= \sqrt ( \frac{1}{r} \int_0^r (wA)^2 dr) [/tex]
