V1 primer=200 volt V2 skunder=10 volt Primer lilitan n1=100 tang Skunder n2=? Berapa jumlah lilitan n2nya?

Vp = 200 V
Vs = 10 V
Np = 100 lilitan

Vp/Vs = Np/Ns
200/10 = 100/Ns
Ns = 10 * 100/200
Ns = 1.000/200
Ns = 5 lilitan

V1/n1 = v2/n2
200/100 = 10/n2
2/1 = 10/n2
n2 = 10.1 / 2
n2 = 10/2
n2 = 5 tang
