Maseketi eDC ari nyore - matambudziko nemhinduro

1. Zvichibva pamufananidzo uri pazasi, sarudza magetsi kuburikidza R₁.

Zvinozivikanwa:

Mudziviriri 1 (R)₁) = 4 Ω

Mudziviriri 2 (R)₂) = 4 Ω

Resistor 3 (R₃) = 8 Ω

Magetsi emagetsi (V) = 40 Volt

Kuda: Mwenje wemagetsi unopfuura nepakati R₁

Solution:

Mwenje wemagetsi unoyerera kubva pakukwanisa kukuru kuenda pakukwanisa kushoma. Kutungamira kwemagetsi mudunhu riri pamusoro kwakafanana nekutungamira kwewachi.

Magetsi anobuda mubhatiri

Kutanga, verengai kuramba kwakaenzana (R). Mushure meizvozvo, verenga magetsi uchishandisa equation ye Mutemo waOmm :

V = IR or Ini = V / R

V= voltage, ini = magetsi, R = kuramba kwakaenzana

Kuramba kwakaenzana:

Mudziviriri R₁ uye chinodzivisa R₂ dzakabatana zvakafanana. Kuramba kwakaenzana:

1 / R₁₂ = 1 / R₁ +1/R₂ = 1/4 + 1/4 = 2/4

R₁₂ = 4/2 = 2 Ω

Mudziviriri R₁₂ uye chinodzivisa R₃ zvakabatana munhevedzano. Kuramba kwakaenzana:

R =R₁₂ +R₃ = 2 + 8 = 10 Ω

Magetsi anobuda mubhatiri:

Ini = V / R = 40 / 10 = 4 A

Simba remagetsi rinobuda mubhatiri ndiro 4 Ampere.

Magetsi emagetsi V_ab uye V_bc

Kirchhoffmutemo wekutanga inotaura kuti pa chero nzvimbo yekusangana, huwandu hwemafungu ese anopinda munosangana hunofanira kuenzana nehuwandu hwemafungu ese anopinda munosangana.

Maererano ne Mutemo wekutanga waKirchhoff, vakagumisa kuti kana magetsi achibuda mubhatiri ari 4 A saka magetsi kuburikidza neab akaenzana ne4 Ampere, saka magetsi kuburikidza nebc i4 Ampere.

Magetsi emagetsi V_ab :

V_ab = Ini_ab R_ab = (4)(2) = 8 Mavolts

Magetsi emagetsi V_bc :

V_bc = Ini_bc R_bc = (4)(8) = 32 Mavolts

Dunhu riri pamusoro apa rakabatana muzvikamu zvakatevedzana kuitira kuti magetsi ese emagetsi ave V = V_ab +V_bc = 8 Mavolts + 32 Mavolts = 40 Mavolts.

Mwenje wemagetsi unoyerera nepakati R₁ = 4 Ω

I₁ =V_ab /R₁ = 8 Volts / 4 Ohms = 2 A

I₂ =V_ab /R₂ = 8 Volts / 4 Ohms = 2 A

Magetsi anobuda mubhatiri i4 A. Kana asvika panzvimbo a, magetsi anokamurwa kuita maviri, magetsi e2 Ampere anoyerera nepakati pe resistor R₁ uye

magetsi e2 A anoyerera nepakati pe resistor R₂. 2 A + 2 A = 4 A.

2. Zvichibva pamufananidzo uri pazasi, sarudza magetsi anoyerera nemu resistor 4-Ω.

Zvinozivikanwa:

Mudziviriri 1 (R)₁) = 6 Ω

Mudziviriri 2 (R)₂) = 4 Ω

Mudziviriri 3 (R)₃) = 1.6 Ω

Mhepo yemagetsi (V) = 16 Volt

Kuda: Mwenje wemagetsi unoyerera nepakati 4 Ω

Solution:

Mwenje wemagetsi unoyerera kubva kumusoro goneko kusvika pakukwanisa kuderera. Kutungamira kwemagetsi mudunhu riri pamusoro kwakafanana nekutungamira kwewachi.

Magetsi anobuda mubhatiri

Kuramba kwakaenzana:

Mudziviriri R₁ uye chinodzivisa R₂ zvakabatana zvakafanana. Chinodzivirira chakaenzana:

1 / R₁₂ = 1 / R₁ +1/R₂ = 1/6 + 1/4 = 2/12 + 3/12 = 5/12

R₁₂ = 12/5 = 2.4 Ω

Mudziviriri R₁₂ uye chinodzivisa R₃ zvakabatana zvakatevedzana. Chinodzivirira chakaenzana:

R =R₁₂ +R₃ = 2.4 + 1.6 = 4 Ω

Magetsi anobuda mubhatiri:

Ini = V / R = 16 / 4 = 4 A

Mhepo yemagetsi V_ab uye V_bc

Zvichibva pamutemo wekutanga waKirchhoff, vakagumisa kuti kana magetsi achibuda mubhatiri ari 4 A saka magetsi kuburikidza neab akaenzana ne4 Ampere, saka magetsi kuburikidza nebc i4 Ampere.

Mhepo yemagetsi V_ab :

V_ab = Ini_ab R_ab = (4)(2.4) = 9.6 Mavolts

Mhepo yemagetsi V_bc :

V_bc = Ini_bc R_bc = (4)(1.6) = 6.4 Mavolts

Dunhu riri pamusoro apa rakabatana muzvikamu zvakatevedzana kuitira kuti magetsi ese emagetsi ave V = V_ab +V_bc = 9.6 Mavolts + 6.4 Mavolts = 16 Mavolts.

Mhepo yemagetsi inoyerera nepakati R₂ = 4 Ω

I₁ =V_ab /R₁ = 9.6 Volts / 6 Ohms = 1.6 A

I₂ =V_ab /R₂ = 9.6 Volts / 4 Ohms = 2.4 A

Simba remagetsi rinobuda mubhatiri i4 A. Kana rasvika panzvimbo imwe chete, simba remagetsi rinokamurwa kuita maviri,

magetsi 1.6 A anoyerera nemu resistor R₁ uye magetsi emagetsi 2.4 A anoyerera nemu resistor R₂. 1.6 A + 2.4 A = 4 A.
