1. Np = 1500

     Ns = 300

     Vs = 3 volt

    Ip = 4 mA = 0,004 A

    Mencari tegangan primer (Vp)

    Np/Ns = Vp/Vs

    1500/300 = Vp/3

    5 = Vp/3

     Vp = 15 volt

     Mencari KUat Arus Sekunder (Is)

     Np/Ns = Is/Ip

     1500/300 = Is/0,004

     5 = Is/0,004

     Is = 0,02 A

     Is = 20 mA

 

2. Np = 1200

     Ns = 40

     Vp = 330 v

     Np/Ns = Vp/Vs

     1200/40 = 330/Vs

     30 = 330/Vs

     Vs = 330/30

     Vs = 11 volt

     Tegangan sekundernya adalah 11 volt

 

3. Pp = 350 watt

     Ps = 70 watt

     Ξ· = Ps/Pp x 100%

         = 70/350 x 100%

         = 1/5 x 100%

         = 20%

     Efisiensi trafo adalah 20%
