Verified answer

22)
Np : Ns = 3 : 1
Vs = 20 volt

Vp : Vs = Np : Ns
Vp : 20 = 3 : 1
Vp = 3 × 20
Vp = 60 volt (pilihan gak ada)

23)
Np = 500 lilitan
Is : Ip = 1 : 5

Is : Ip = Np : Ns
1 : 5 = 500 : Ns
Ns = 500 × 5
Ns = 2500 lilitan (B)

24)
N1 = 100 lilitan
N2 = 250 lilitan
V1 = 40 volt

V1 : V2 = N1 : N2
40 : V2 = 100 : 250
40 × 250 = 100 × V2
10000 = 100V2
V2 = 10000/100
V2 = 100 volt (A)

25)
Np : Ns = 5 : 3
Is = 3 A

Is : Ip = Np : Ns
3 : Ip = 5 : 3
3 × 3 = 5 × Ip
9 = 5Ip
Ip = 9/5
Ip = 1,8 A (A)
