Mutemo wechipiri waKirchhoff unoti shanduko yesimba remagetsi padenderedzwa redenderedzwa rakavharwa izero. Mutemo wechipiri waKirchhoff wakavakirwa pamutemo wekuchengetedza simba, uyo unoti simba risingaperi.
Kuti unzwisise izvi zviri nani, fungidzira chaji yemagetsi ichifamba mu closed circuit, sezviri pamufananidzo. Kana chaji yemagetsi inopfuura nepa kupikisa magetsi (R), iyo simba remagetsi inoderedzwa nekuti inoshandiswa pazvirambidzo izvi. Kana chaji yemagetsi ikapfuura neimwe resistance yemagetsi, simba remagetsi rinodzikira zvakare nekuti rinoshandiswazve parisistance. Uyezve, kana chaji yemagetsi ikapfuura nepanobva voltage kubva pa low potential kuenda pa high potential, simba remagetsi rinowedzera. Painodzokera panzvimbo yayo yekutanga, simba remagetsi rinofanana nerakare, uko shanduko musimba remagetsi rinova zero. Pakushandisa KirchhoffMutemo wechipiri wedunhu remagetsi, tinoshandisa shanduko yemagetsi, kwete shanduko yesimba remagetsi.
Dunhu rakafanana neriri pamufananidzo uri pamusoro rinogona kuongororwa uchishandisa mutemo weOhm (V = IR) uye equation yekudzivirira kweseji kana kuramba kwakafanana. Madunhu akaomarara akadai semufananidzo anogona kuongororwa uchishandisa mutemo wekutanga waKirchhoff uye mutemo wechipiri waKirchhoff.
Heano mimwe mitemo inokosha pakushandisa mutemo wechipiri waKirchhoff kuongorora dunhu.
Kutanga , sarudza divi remagetsi, kungave rewachi kana rewachi. Kana mhinduro iri negative, divi chairo remagetsi riri munzira yemagetsi yakasarudzwa. Kana mhinduro iri positive, divi chairo remagetsi rakafanana negwara remagetsi akasarudzwa.
Chechipiri , kana uchipfuura nepanobva voltage kubva pa high potential kuenda pa low potential (kusvika -), pane kudzikira kwe electrical voltage zvekuti voltage yacho inenge iri negative (ΔV = -ε). Kusiyana neizvi, kana ichifamba kubva pa low potential kuenda pa high potential (- kusvika), pane kuwedzera kwe electrical voltage zvekuti voltage yacho inenge yakanaka (ΔV = ε).
Chechitatu , kana ichipinda nepakati pesimba remagetsi, kana denderedzwa riri munzira yemagetsi, voltage iri negative (V = – IR). Kusiyana neizvi, kana denderedzwa riri munzira yakatarisana nenzira yemagetsi, voltage yemagetsi iri positive (ΔV = IR).
Dambudziko remuenzaniso 1:
R1 = 200 Ω uye R2 = 300 Ω. ε = 12 Volts. Verenga magetsi ari kuyerera mudunhu uchishandisa KirchhoffMutemo wechipiri!
Solution:
Kutungamira kwenzira yewachi.
– IR 1 – IR 2 + ε = 0
– 200 I – 300 I + 12 = 0.
– 500 I + 12 = 0
– 500 I = – 12
Ini = 12 / 500
Ini = 0.024 A
Kana zvikaverengerwa uchishandisa mutemo weOhm uye fomura yemusanganiswa wema resistors akatevedzana:
R = R 1 + R 2 = 200 + 300 = 500 Ω.
Kuenzana kwemutemo weOhm:
V = IR
Ini = V / R = 12 / 500 = 0.024 A.
Dambudziko remuenzaniso 2:
R 1 = 100 Ω, R 2 = 200 Ω, R 3 = 300 Ω, ε 1 = 9 Volts, ε 2 = 12 Volts. Verenga hukuru uye divi remagetsi ari mudunhu!
Solution:
Sarudza divi remagetsi uye divi rerobho rakafanana nedivi rewachi.
– IR 1 – IR 2 – ε 1 – IR 3 + ε 2 = 0
– 100 I – 200 I – 9 – 300 I + 12 = 0
– 100 I – 200 I – 300 I + 3 = 0
– 600 I + 3 = 0
– 600 I = – 3
Ini = 3 / 600
Ini = 0.005 A
Mwenje wemagetsi wakanaka zvekuti divi rawo rinoenderana negwara rakasarudzwa.
