Question

Jawab yg dilingkari & gambar ke 3 no 18 (dengan langkah cara)

Answer 1

Nomor 33
Ip = 1,5 A
Np = 500 lilitan
Ns = 125 lilitan
Is = ?
Is / Ip = Np / Ns
Is / 1,5 = 500/125
Is = 4 * 1,5 = 6 Ampere

Nomor 34
Pp = 120 watt
Ps = 90 watt
η = ?
η = Ps/Pp * 100%
η = 90/120 * 100% = 75%

Nomor 35 teksnya ada yang hilang

Nomor 37
Ns = 800 lilitan
Np = 80 lilitan
Ip = 4 A
Is = ?
Is / Ip = Np / Ns
Is / 4 = 80 / 800
Is = 0,4 Ampere

Nomor 4
Np = 120 lilitan
Ns = 80 lilitan
Ip = 6 A
a) Jenis travo adalah step down, karena Ns<Np
b) Is / Ip = Np / Ns
Is / 6 = 120 / 80
Is = 9 Ampere
