Question

Jika tegangan primer 220 kuat arus primer dan arus sekunder 5A dan 15A hitunglah tegangan sekunder apabila efesiensi trafonya 90%

Answer 1

Verified answer

Vp = 220 v
Ip = 5 A
Is = 15 A
n = 90 %
Vs?

penyelesaian:
Vs = Vp × Ip × n / Is × 100%

Vs = 220 × 5 × 90% / 15 × 100%

Vs = 22 × 45 / 15

Vs = 22 × 3

Vs = 66 volt
