Voltage ma loops o transformers - faʻafitauli ma fofo

1.

E fa'avae i luga o le laulau o lo'o i luga, saili le R ma le P.

O le fua fa'atatau a le Transformer:

V_s N_p = N_s V_p ma le V_p I_p =V_s I_s

V_s = voltage lona lua, V_p = autū volitigaN_s = matasele lona lua, N_p = matasele autū_, I_p = autū i le taimi nei, O aʻu_s = tafega lona lua

Voltage autū (V _p )

V _p I _p = V _s I _s

V _p (4) = (10)(80)

V _p = 800 / 4

Vp = R = 200 _Volt

Matasele lona lua (N _s )

Vs Np = _Ns Vp_​​​

(10)(600) = N _s (200)

6000 = 200 N _s

Ns = 6000 _/ 200

N _s = P = 30 matasele

2.

E fa'avae i luga o le laulau o lo'o i luga, saili le K ma le L.

Fofo:

Tafe lona lua (I _s ) o le transformer 1:

V _p I _p = V _s I _s

(200)(3) = (300)(I _s )

I _s = 600 / 300

I _s = K = 2 A

Voltage lona lua (Vs ₎ o le transformer 2:

V _p I _p = V _s I _s

(40)(0,75) = Vs ₍ 1)

Vs ₌ L = 30 Volt

3.

E fa'avae i luga o le laulau o lo'o i luga, saili le P ma le Q.

Fofo:

Voltage autū (V _p )

Vs Np = _Ns Vp_​​​

(220)(300) = (600) V _p

(220)(3) = (6) V _p

660 = 6 V _p

V _p = 660 / 6

Vp = P ₌ 110 Volt

Tafe autū (I _p )

V _p I _p = V _s I _s

(110)(I _p ) = (220)(2)

(110)(1 _p ) = 440

I _p = 440 / 110

I _p = Q = 4 A
