perbandingan primer dengan lilitan sekunder pada transformator 2:5 jika tegangan yang masuk 110 volt dan arus mengalir 2 ampere hitung lah a. tegangan output b.

diket :
Np : Ns = 2 : 5
Vp = 110 v
Ip = 2 A
dit : Vs , Is & data trafo
Jwb :

a # Tegangan our put
Vs = ( Ns . Vp ) / Np
Vs = ( 5 . 110 ) / 2
Vs = 550 / 2
Vs = 275 volt

b # Arus out put
Is = ( Vp . Ip ) / Vs
Is = ( 110 . 2 ) / 550
Is = 220 / 550
Is = 0,4 A

c # data trafo
Np = 2 lilitan
Ns = 5 lilitan
Vp = 110 v
Vs = 550 v
Ip = 2 A
Is = 0,4 A

Np < Ns
Vp < Vs
Ip > Is
