Question

Maka kiat arus sekundernya adalah?​

Answer 1

Jawaban:

Is = 0,9 A

Penjelasan:

Vp/Vs = Np/Ns

220/Vs = 2000/4000

Vs = 220/(1/2)

Vs = 440 v

Daya Input

Pp = Vp. Ip = 220. 2

Pp = 440 watt

Daya output

η = Ps/Pp

0,9 = Ps/440

Ps = 0,9. 440

Ps = 396 watt

Arus sekunder

Ps = Vs. Is

Is = Ps/Vs = 396/440

Is = 0,9 A

Answer 2

Diketahui:

Np = 20.000

Vp = 220 V

Ip = 2 A

Ns = 4.000

Cara mengerjakan:

Efisiensi trafo = Ps/Pp × 100%

90% = IsVs/IpVp × 100%

90% = IsVs/2.220 × 100%

90% = IsVs/440 × 100%

90/100 = Ps/440

Ps × 100 = 440 × 90

Ps = 396 watt

Ps = Vs × Is

Cari Vs terlebih dahulu.

Vs/Vp = ns/np

Vs/220 = 4000/20.000

Vs = 44

Ps = Vs × Is

396 = 44 × Is

Is = 396 ÷ 44 = 9 A

Maaf kalo salah, semoga membantu c:
