trafo dengan tegangan 220 volt menyebabkan kuat arus primer 10 ampere. jika perbandingan jumlah primer dan sekunder 2:15 . hitunglah tegangan sekunder dan kuat

Ns/Np = Vs/Vp = ip/is

15/2 = Vs/220
Vs = 1650V

15/2 = 10/is
is = 4/3 = 1,3 A

#semoga membantu

Diketahui:
Vp = 220 V
Ip = 10 A
Np : Ns = 2 : 15
Vs = ...
Is = ...

Jawab:
Ns/Np = Vs/Vp
15/2 = Vs/220
2Vs = 15 × 220
2Vs = 3.300
Vs = 3.300/2
Vs = 1.650

Ns/Np = Ip/Is
15/2 = 10/Is
15Is = 20
Is = 20/15
Is = 4/3 = 1,33 A
