Voltaji na loops nke transformers - nsogbu na ngwọta

1.

Dabere na tebụl dị n'elu, chọta R na P.

ngwọta

Usoro nhazi nke transformer:

V_s N_p = N_s V_p na V_p I_p = V_s I_s

V_s = voltaji nke abụọ, V_p = isi voltajiN_s = mgbachi nke abụọ, N_p = mgbachi mbụ_, I_p = isi ugbu a, M_s = nke abụọ ọkụ

Voltaji bụ isi (V _p )

V _p I _p = V _s I _s

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

V _p = 800 / 4

V _p = R = Volt 200

Oghere nke abụọ ( _Ns )

Vs _N p ₌ N _s V _p

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

6000 = 200 N _s

N _s = 6000 / 200

N _s = P = loops 30

2.

Dabere na tebụl dị n'elu, chọta K na L.

Ngwọta:

Ọkụ nke abụọ ( _Is ) nke transformer 1:

V _p I _p = V _s I _s

(200)(3) = (300)( _Is )

Is ₌ 600 / 300

I _s = K = 2 A

Voltaji nke abụọ (Vs ₎ nke transformer 2:

V _p I _p = V _s I _s

(40)(0,75) = Vs _s (1)

Vs ₌ L = Volt 30

3.

Dabere na tebụl dị n'elu, chọta P na Q.

Ngwọta:

Voltaji bụ isi (V _p )

Vs _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 = Volt 110

Ọkụ isi ( _Ip )

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
