Verified answer

Diket :
Vp = 240 b
Np = 300
Ns = 30
Rs = 8 ohm
dit : Arus primer
jwb :
#Tegangan sekunder
Vs = ( Ns . Vp ) / Np
Vs = ( 30 . 240 ) / 300
Vs = 7200 / 300
Vs = 24 volt

#Arus sekunder
Is = Vs / Rs
Is = 24 / 8
Is = 3 A

# Arus primer
Ip = ( Is . Vs ) / Vp
Ip = ( 3 . 24 ) / 240
Ip = 72 / 240
Ip = 0,3 A
