Chinyorwa nezveResistors munhevedzano
Kana ma resistors akabatana sezvakaratidzwa mumufananidzo, ma resistors akarongwa akatevedzana. Resistor kana resistance yemagetsi iri kutaurwa nezvayo inogona kunge iri muchimiro che resistor components, mwenje, kana imwe resistance yemagetsi.
Chaja yemagetsi inofamba nepakati pekudzivirira 1 (R)1) = ivo electric charge inofamba kuburikidza nekuramba 2 (R)2) = chaji yemagetsi inofamba nepakati pekudzivirira 3 (R)3). Magetsi emagetsi (I) ishaja yemagetsi inoyerera panguva yakati (I = Q / t), saka magetsi emagetsi kuburikidza nekuramba 1 (I1) = magetsi kuburikidza nekudzivirira 2 (I2) = magetsi kuburikidza nekudzivirira 3 (I3Pamasvomhu, simba remagetsi rose (I) = I1 = Ini2 = Ini3.
Kusiyana neizvi, magetsi emagetsi (V) anodzikira kana magetsi achifamba nepakati pe resistor yega yega. Magetsi anonziwo electric potential difference, i energy yemagetsi payuniti yega yega ye electric charge. Magetsi anodzikira nekuti magetsi anoshandiswa mu resistor yega yega yemagetsi. Saka, magetsi ese (V) akaenzana nehuwandu hwemagetsi mu resistor yega yega. Pamasvomhu, magetsi ese (V) = V1 +V2 +V3V = IR saka equation yemagetsi emagetsi ndeye V = IR1 + IR2 + IR3.Magetsi anoyerera pa resistor yega yega akaenzana zvekuti equation iyi inoshanduka kuita V = I (R1 +R2 +R3).
Zvichibva pa equation iri pamusoro apa, zvinogona kugumiswa kuti total electrical resistance (R) kana kuti equity yakaenzana ye electrical resistance
iyo yakabatana munhevedzano yakaenzana nehuwandu hwesimba remagetsi rega rega, maererano nemasvomhu R = R1 +R2 +R3Kana paine ma resistors maviri chete akatevedzana, resistor yakaenzana (R) = R1 +R2Kana paine ma resistors mana akatevedzana, resistor yakaenzana (R) = R1 +R2 +R3 +R4Saizvozvowo, kana paine ma resistors mashanu kana kupfuura mashanu akabatana akatevedzana.
Dambudziko remuenzaniso 1:
Kana zvichizivikanwa, R1 = 2 Ω, R2 = 3 Ω uye R3 = 4 Ω. Ma resistors ese matatu akabatana munhevedzano. Chii chinonzi resistor yakaenzana? (Ω = Ohm ).
Solution:
R = R 1 + R 2 + R 3 = 2 + 3 + 4 = 9 Ω.
Mhedzisiro iyi inoratidza kuti resistance yakaenzana yakakura kupfuura kukosha kweresistor dzakabatana mu series.
Dambudziko remuenzaniso 2:
Ma resistors maviri R 1 = 50 Ω uye 50 Ω akabatana mumutsara uye akabatana nebhatiri re12 Volt.
(a) Kuramba kwakaenzana
(b) Mhepo yemagetsi inopinda nemuchina wega wega unodzivisa
Solution:
(a) R = R 1 + R 2 = 50 Ω + 50 Ω = 100 Ω.
(b) I = V / R = 12 Volts / 100 Ω = 0.12 A
