Sebuah trafo dihubungkan dengan tegangan pln 100 V menyebabkan kaut arus pda kumparan primer 10 A .jika perbandingan jumlah liltan primer dan sekunder 1:25 hitunglah:a.tegangan pda kumparan sekunder b.kuat arus pada kumparan sekunder

Dik= • Vp = 100 v • Ip = 10 A • Np : Ns = 1 : 25
dit= a. Vs b. Is
jawab
a. tegangan sekunder Vp / Vs = Np / Ns 100 / Vs = 1 / 25 Vs = ( 25 × 100 ) : 1 Vs = 2500 V
b. kuat arus pada kumparan sekunder Is / Ip = Np / Ns Is / 10 = 1 / 25 Is = ( 10 × 1 ) ÷ 2500 Is = 10 ÷ 2500 Is = 0,004 A
Np = 1
Ns = 25
Ip = 10 A
Dit : Vs = ?
Is = ?
Jwb :
• Vp = 100 v
• Ip = 10 A
• Np : Ns = 1 : 25
dit=
a. Vs
b. Is
jawab
a. tegangan sekunder
Vp / Vs = Np / Ns
100 / Vs = 1 / 25
Vs = ( 25 × 100 ) : 1
Vs = 2500 V
b. kuat arus pada kumparan sekunder
Is / Ip = Np / Ns
Is / 10 = 1 / 25
Is = ( 10 × 1 ) ÷ 2500
Is = 10 ÷ 2500
Is = 0,004 A
