Tolong dijawab menggunakan cara kak

Answer 1

Transformator 1 mencari Is = Q
Is = Vp / Vs = Is / Ip
    = 400 / 1000 = Is / 4
    = 400.4 = 1000 Is
    = 1600 = 1000
Is = 1600 / 1000
    = 1,6 A
Ip > Is = Transformator step up
Transformator 2 mencari Ip = P
Ip = Vp / Vs = Is / Ip
    = 1500 / 500 = 3 / Ip
    = 1500 Ip = 1500
Ip = 1500 / 1500
    = 1 A
Ip < Is = Transformator step down
Jawaban = A
