Chinyorwa nezveResistors chakafanana
Kana ma resistors akabatana sezviri pamufananidzo, ma resistors akabatana zvakafanana.
Mwenje wemagetsi (magetsi = kuchaja kwemagetsi kunoyerera panguva imwe chete) unopinda panzvimbo yekubatanidza wakafanana nemagetsi anobuda panzvimbo yekubatanidza. Kune nzvimbo dzakasiyana siyana kuitira kuti huwandu hwemagetsi ese = huwandu hwemagetsi anoyerera munzvimbo imwe neimwe yekubatanidza. Pamasvomhu, I = I 1 + I 2 + I 3 . Kunyange zvazvo musiyano wemagetsi kana voltage yemagetsi munzvimbo imwe neimwe yekubatanidza wakafanana.
I = V/R saka equation iri pamusoro inoshanduka kuita I = V/R 1 + V/R 2 + V/R 3 . Voltage yemagetsi yakaenzana, saka equation iyi inoshanduka kuita I = V (1/R 1 + 1/R 2 + 1/R 3 ). Kana resistance yakaenzana iri 1/R saka I = V (1/R). Saka, 1/R = 1/R 1 + 1/R 2 + 1/R 3.
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/R 1 + 1/R 2 = 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 1 maviri = 50 Ω uye 50 resistors akabatana mumutsara uye akafanana, akabatana nebhatiri re12 Volt. Sarudza:
(a) Kuramba kwakaenzana
(b) Mhepo yemagetsi inopinda nemuchina wega wega unodzivisa
Solution:
(a) Zvinodzivirira zvakatevedzana:
R = R 1 + R 2 = 50 Ω + 50 Ω = 100 Ω.
Vadziviriri vari pamwe chete:
1/R = 1/R 1 + 1/R 2 = 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.
