Indlela ukwenza resistor ukufana?

Ukuze ukulawula ubungakanani ekhoyo kunye ombane kwisiphaluka eyenziwe resistors compound ethile. izinto Series-elidityaniswe ukunciphisa ngoku kwisekethe, iindawo eziyelelene yi ngaxeshanye ukudala enye idrophu umbane ezongezelelweyo, xisweswo xi ixabiso umahluko okunokwenzeka kubasebenzisi aba kwikhonkco efanayo.

Ungasebenzisa resistor omnye ixabiso olifunayo, kodwa akusoloko kusenzeka ukuba benze izibalo ezingayimfuneko ukuqaphela ixabiso eliphezulu. Ngako oko ke kucetyiswa ukuba ukhethe uxhathiso ngu intlanganisela magnitudes ezahlukeneyo.

Umdibaniso engumzekelo resistors kwenziwa ngokudibanisa Ekuthwaseni kunye iziphelo izinto zonke udumbo enye. Ngenxa yoko, ujikeleze idaliwe apho ukuhla ombane iyonke kwisekethe iphela kuxhomekeka kwixabiso isiqalelo ngasinye.
Uxhathiso elipheleleyo resistors enxulumene ngaxeshanye, ibalwa yi indlela ekhethekileyo.

Khumbula ukuba wenze uxhulumaniso parallel of resistors, kweelana lilonke zonke izinto ziya nakanjani incinane uxhathiso incinane ezibandakanywe kwisekethe.

Nangona kunjalo, kukho ezinye iimeko ezizodwa, ongayi kuba nako kulityalwa. Ukuba wesekethe yenziwe resistors ezimbini kuphela, nokumelana sabo setotali zibalwe umahluko phakathi kwesiphumo sophinda phindo kunye isiphumo: Rmain = R1R2 / R1 + R2.

Ityala ekhethekileyo ngakumbi yikhompawundi leyo ifakiwe resistors ezininzi ixabiso ukumelana efanayo. Kulo mzekelo, ixabiso lilonke umiselwa ixabiso umahluko linani lweziqalelo ukumelana, okt: Rmain = R1 / n.

Ekubeni uxhulumaniso engumzekelo resistors - node ezimbini, kucacile ukuba umahluko ubuchule kwanolwazi abasele benalo - oko kunto-nye njengoko umahluko ezinokubakho phakathi kwezi ndawo zimbini. Ngoko ke, kusengqiqweni ukugqiba ukuba ombane ngamnye izinto bayalingana. Kubonakala ngathi le nto: U = U1 + U2 + U3 + ... + Un ..

Ukuba zombini iindawo ukuba kusekwe uqhagamshelwano engumzekelo resistors edityaniswe ngqo iterminal umthombo wamandla, le ombane nganye resistances iya kulingana ukuya ombane ukuba ivelisa umthombo ngokwayo: U1 + U2 + U3 + ... + Un = U ..

Enye into le khompawundi of resistors uqhagamshelo enxuseneyo elijikeleza umsinga wombane. It isasazwa ngokusebenzisa pali umlinganiselo reverse ukuya ukungawi kule mimandla. Ngamanye amazwi, kokukhona ukuxhathisa, incinci ngoku, kwaye Kwelinye icala, kungona lwangoku, inowuthi uxhathiso. Nguwo lowo wokuqala umthetho Ohm esithi: I = U / R.

Le ngoku zizonke Lendawo i udibaniso lwamaxabiso ezikhoyo kwisebe ngalinye ngokwahlukeneyo. Ngapha koko, izityholo angakhuli iindawo, ngoko kufanele kuphawulwe kuqala umthetho Kirchhoff kaThixo, yona ithi: ". Umdibaniso imisinga, ezifakwe kwi udumbo ilingana isixa imisinga ukuba baphume kuwo" Sinokuthi lula - isixa imisinga kwi udumbo ngu zero. Kwaye ibinzana esibhaliweyo ngolu hlobo lulandelayo: "Xa zidityanisiwe ezi imisinga ilingana zero."

Thaca apha ke imithetho echaphazelekayo kumphathi wesekethe ngaphandle inductance kunye capacitance. Ukuba uxhulumaniso engumzekelo resistors i sekethe kunye coil okanye capacitor, kuyimfuneko ukufumana ngenxa ukuvimba lweziqalelo bonke. Ukuze wenze oku, ukubala inductance kunye capacitance.
