Chinyorwa nezveResistors chakafanana

Kana ma resistors akabatana sezviri pamufananidzo, ma resistors akabatana zvakafanana.

The magetsi (magetsi = magetsi anoyerera panguva imwe chete) anopinda panzvimbo yekubatanidza magetsi akafanana nemagetsi anobuda panzvimbo yekubatanidza magetsi. Kune nzvimbo dzakasiyana siyana kuitira kuti magetsi ese = huwandu hwemagetsi anoyerera munzvimbo imwe neimwe yekubatanidza magetsi. Pamasvomhu, I = I₁ + Ini₂ + Ini₃Kunyange zvazvo musiyano wesimba remagetsi kana magetsi emagetsi mumharadzano yega yega yakafanana.

I = V/R saka equation iri pamusoro inoshanduka kuita I = V/R₁ + V/R₂ + V/R₃Voltage yemagetsi yakaenzana, saka equation iyi inoshanduka kuita I = V (1/R)₁ +1/R₂ +1/R₃). Kana resistance yakaenzana iri 1/R saka I = V (1/R). Saka, 1/R = 1/R₁ +1/R₂ +1/R₃.

Maseketi akafanana ane mukana, kana magetsi emagetsi kune rimwe resistor akatyoka, magetsi emagetsi anoramba achiyerera kune mamwe ma resistor. Nepo mumatanho akatevedzana, kana magetsi emagetsi mune rimwe resistor akatyoka, ma resistor ese haazopihwe magetsi.

Dambudziko remuenzaniso 1:

Zvinozivikanwa kuti R₁ = 2 Ω, R₂ = 3 Ω. Ma resistors ese ari maviri akafanana. Chii chinonzi resistor yakaenzana? (Ω = Ohm).

Solution:

1/R = 1/R₁ +1/R₂ = 1/2 + 1/3 = 3/6 + 2/6 = 5/6

R = 6/5 = 1.2 Ω.

Mhedzisiro iyi inoratidza kuti kukosha kwe resistor kwakaenzana kudiki pane kukosha kwe resistor yega yega yakafanana.

Dambudziko remuenzaniso 2:

MaR maviri₁ = 50 Ω uye 50 resistors zvakabatana zvakatevedzana uye zvakafanana, zvakabatana nebhatiri re12 Volt. Sarudza:

(a) Kuramba kwakaenzana

(b) Mhepo yemagetsi inopinda nemuchina wega wega unodzivisa

Solution:

(a) Zvinodzivirira zvakatevedzana:

R = R₁ +R₂ = 50 Ω + 50 Ω = 100 Ω.

Vadziviriri vari pamwe chete:

1/R = 1/R₁ +1/R₂ = 1/50 + 1/50 Ω = 2/50

R = 50/2 = 25 Ω

(b) Zvinodzivirira zvakatevedzana:

I = V / R = 12 Volts / 100 Ω = 0.12 A

Vadziviriri vari pamwe chete:

I = V / R = 12 Volts / 25 Ω = 0.48 A

Mhedzisiro iyi inoratidza kuti magetsi ese ari kuyerera mudunhu rakafanana akakura, nepo magetsi ese ari kuyerera munhevedzano ari madiki.
