Muedzo weTransformer:

V_s N_p = N_s V_p uye V_p I_p =V_s I_s

V_s = voltage yechipiri, V_p = chikuru voltageN_s = zvishwe zvechipiri, N_p = zvishwe zvekutanga_, I_p = chikuru mafambiro, Ini_s = simba rechipiri

Voltage yekutanga (V _p )

V _p I _p = V _s I _s

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

V _p = 800 / 4

V _p = R = 200 Volt

Zvidimbu zvechipiri ( _Ns )

V _s N _p = N _s V _p

(10)(600) = Ns ₍ 200)

6000 = 200 _Ns

N ₌ 6000 / 200

N _s = P = 30 zvishwe

2.

Zvichibva patafura iri pamusoro, tsvaga K naL.

Solution:

Simba rechipiri ( _Is ) re 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 yechipiri (V _s ) yetransformer 2:

V _p I _p = V _s I _s

(40)(0,75) = Vs ₍ 1)

Vs ₌ L = 30 Volt

3.

Zvichibva patafura iri pamusoro, tsvaga P na Q.

Solution:

Voltage yekutanga (V _p )

V _s N _p = N _s V _p

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

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

660 = 6 V _p

V _p = 660 / 6

V _p = P = 110 Volt

Simba rekutanga (I _p )

V _p I _p = V _s I _s

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

(110)(I _p ) = 440

I _p = 440 / 110

I _p = Q = 4 A
