Np = 100 lilitan Ns = 10000 lilitan Vp = 12 volt Ip = 5 ampere
A) Pp = ___? B) Vs = ___? C) is = ___? Jika efisiensi 100% D) is = ___? Jika efisiensi 80%
Jawab : A) Pp = Vp. Ip Pp = 12.5 Pp = 60 watt
B) Vs/Vp = Ns/Np Vs/12 = 10000/100 Vs = 1200 volt
C) Ps = efisiensi. Pp Vs.Is = 100%. Pp 1200.Is = 100%.60 Is = 1/20 ampere Is = 0,05 ampere
Ns = 10000 lilitan
Vp = 12 volt
Ip = 5 ampere
A) Pp = ___?
B) Vs = ___?
C) is = ___? Jika efisiensi 100%
D) is = ___? Jika efisiensi 80%
Jawab :
A) Pp = Vp. Ip
Pp = 12.5
Pp = 60 watt
B) Vs/Vp = Ns/Np
Vs/12 = 10000/100
Vs = 1200 volt
C) Ps = efisiensi. Pp
Vs.Is = 100%. Pp
1200.Is = 100%.60
Is = 1/20 ampere
Is = 0,05 ampere
D) Ps = efisiensi. Pp
Vs.Is = 80%. Pp
1200.Is = 0,8.60
Is = 0,04 ampere
