tolong di bantu jawab yh

Diket :
Vp = 20 v
Vs = 22 v
Is = 2 A

Dit : Np : Ns , Ps , Pp & Ip......?

Jwb :

a# Perbandingan lilitan

Np : Ns = Vp : Vs
Np : Ns = 20 : 22
Np : Ns = 10 : 11

b #Daya sekunder ( lampu)

Ps = Vs . Is
Ps = 22 . 2
Ps = 44 watt

c #Daya primer ( pln )

krn teafo ideal maka daya primenya :


Pp = Ps
Pp = 44watt

d # Arus primer ( pln )

Ip = Pp / Vp
Ip = 44 / 20
Ip = 2,2 A
