Quick Faraday equation

  1. Apr 24, 2009 #1
    I have this equation and the following values for a transformer

    Bmax= (V1)/(4N1fA)

    V1=10v, i.e. 20v peak-to-peak
    N1=40 turns
    A=76x10-6 m2

    When i substitute in the voltage, do i use the 10v, or the peak to peak, or would i have to convert to Vrms

    the Faraday equation is

    Vpeak= (2 pi f) Bpeak A N

    So Bpeak= 10/(6.28 f A N) = 0.104 Tesla
