Sebuah transformator step up terdiri atas kumparan primer dgn 100lilitan dan kumparan sekunder 10.000 lilitan. jika tegangan pada kumparan primer 12 v dan kuat arus 5A, tentukan: a.) daya input b.) tegangan pd kumparan sekunder c.) kuat arus pd kumparan sekunder jika efesiensi trafo 100%
mendokusai
A. Pp = Ip Vp Pp = 5 12 Pp = 60 Watt ----------------------------------------------------- b. Vs = Ns Vp / Np Vs = 10000 12 / 100 Vs = 1200 Volt ----------------------------------------------------- c. η = 100% Ps = Pp Is Vs = Pp Is = Pp / Vs Is = 60/1200 Is = 1/20 Is = 0,05 Ampere
Pp = Ip Vp
Pp = 5 12
Pp = 60 Watt
-----------------------------------------------------
b.
Vs = Ns Vp / Np
Vs = 10000 12 / 100
Vs = 1200 Volt
-----------------------------------------------------
c.
η = 100%
Ps = Pp
Is Vs = Pp
Is = Pp / Vs
Is = 60/1200
Is = 1/20
Is = 0,05 Ampere
Semoga membantu :)
