Homework Help: Peak voltage output of a generator

  1. May 24, 2007 #1
    1. The problem statement, all variables and given/known data
    A 400 loop circular armature coil with a diameter of 5cm rotates at 60rev/s in a uniform magnetic field of strength 1T.

    a) What is the peak voltage output of the generator?
    b) What is the RMS voltage output of the generator?

    3. The attempt at a solution

    a) My answer seems a tad large, I think I'm doing something wrong but can't quite pick it...:yuck:

    b) RMS=ε*[1/√(2)]
    (Leaving it for now as it depends on the answer from part a)

    Convert 5cm to 0.05m. Reduces answer by a factor of 10000.

    why is sin(wt) = 1?

    is it because its a dc generator?
