Transformator stand-up dengan jumlah lilitan primer 400, lilitan sekunder 800 tegangan primer 100, daya watt listrik 500 watt, efisiensi trafo 80% A. Tegangan s

Diketahui:
Trafo Step up
Np = 400
Ns = 800
Vp = 100
Pp = 500 watt
n = 80%

Ditanya : 
a.Vs=..?
b.Ps=...?
c.Is=...?
d.Ip=...?

Jawab:

a.Np/Ns = Vp/Vs
400/800 = 100/Vs
Vs = 100x800/400
Vs = 200 v

b. n = Ps/Pp x 100%
80 = Ps/500 x 100 
80 = Ps/5
400 watt = Ps

c. n = Np.Is/Pp x 100 %
80 = 400.Is/500 x100
80 = 400.Is/5
80 = 80 Is
1 A = Is 

d. Is/Ip = Np/Ns
1/Ip = 400/800
Ip = 800/400
Ip = 2 A
