Answer 1

Verified answer

9) diket :
Vp = 200 v
Ip = 2A
Is = 2 . Ip = 4 A
dit : pebandingan Np : Ns
jwb :
Np : Ns = Is : Ip
Np : Ns = 4 : 2
Np : Ns = 2 : 1
jwb yg C
21 )diket :
Vp = 200 v
Vs = 20 v
Is = 4 A
dit : Arus primer
jwb :
Ip = ( Vs . Is ) / Vp
Ip = ( 20 . 4 ) / 200
Ip = 80 / 200
Ip = 0,4 A
jwb yg B harusnya 0,4 bukan 0,04
26) diket :
Ip = 12 A
Np = 40
Ns = 80
dit : Arus sekunder
Is = ( Np . Ip ) / Ns
Is = ( 40 . 12 ) / 80
Is = 480 / 80
Is = 6 A
jawb yg D
27) diket :
P = 200 MW = 200.000.000 watt
V = 250 KV = 250.000 Volt
dit : Arus listrik
jwb '
I = P / V
I = 200.000.000 / 250.000
I = 800 A
jwb yg A
