Verified answer

Materi : Medan Magnetik dan Induksi Elektromagnetik
Sub bab : Trafo

Diketahui :
Is = 5 A
Vp = 220 v
Pp = 2200 watt

Ditanya :
a) Np
b) Ns
c) Ip
d) Vs
e) Ps
f) Jenis trafo

Penyelesaian :
*Cari Kuat arus Primer
c) Pp = Vp. Ip
2200 watt = 220v. Ip
Ip = 10 A

*Cari tegangan sekunder
d) Vp/Vs = Is/Ip
220 v/Vs = 5 A/10 A
220 v/Vs = 1/2
Vs = 440 v

*Cari lilitan primer
a) Vp/Vs = Np/Ns
220v / 440 v = Np/Ns
1/2 = Np/Ns
Np = 1/2 Ns

*Cari lilitan sekunder
b) Np = 1/2 Ns
Ns = 2Np

*Cari Daya sekunder
e) Ps = Vs. Is
Ps = 440 v. 5 A
Ps = 2200 watt

*Jenis trafo
- Vp < Vs
- Ip > Is
- Np < Ns

Maka, jenis trafo : step-up

semoga membantu
