Kodi kuchita resistor yomweyi?

Kuti zonse kuchuluka kwa panopa ndi voteji mu dera anapanga resistors makamaka pawiri. Series-olumikizidwa zinthu zoletsa ziliri pa dera, ndi zolumikizana kufanana kulenga zina voteji dontho, n'kusowa lingathe mtengo kusiyana ogula amene ali mu unyolo chomwecho.

Mukhoza kugwiritsa ntchito limodzi resistor mtengo wolakalakika, koma Sizotheka kuti anapezazo ndi zothandiza kupeza phindu mulingo woyenera. Choncho m'pofunika kusankha kukana ndi osakaniza magnitudes osiyana.

Kugwirizana yomweyi resistors anachita ndi kulumikiza zoyambira ndi malekezero a mbali zonse mu mfundo imodzi. Choncho, dera analenga kumene okwana voteji dontho kudutsa dera kutengera ndi phindu lililonse amafotokozera.
Kulimbikira okwana resistors zogwiritsidwa mu kufanana, kuchita masamu ndi chilinganizo wapadera.

Kumbukirani kuti ngati munapanga kugwirizana kufanana kwa resistors, kulimbikira okwana zinthu zonse Ndithu kakang'ono kuposa kulimbikira zing'onozing'ono m'gulu dera la.

Komabe, pali nthawi zina zapadera, amene sakhoza kuiwalika. Ngati dera la ndikoyambitsidwa resistors awiri okha, kukana awo okwana masamu monga kusiyana mankhwala awo ndi ndalama; Rmain = R1R2 / R1 + R2.

Nkhani zina zapadera ndi pawiri amene m'gulu resistors ambiri kufunika yomweyo kukana. Pankhaniyi, phindu okwana mtima mtengo kusiyana kwa chiwerengero cha zinthu kukana, mwachitsanzo: Rmain = R1 / N.

Popeza kugwirizana yomweyi resistors - awiri mfundo, zikuonekeratu kuti kusiyana angathe awo - ndi chimodzimodzi monga kusiyana ulipo pakati pa mfundo ziwirizi. Choncho, n'zomveka kunena kuti voteji aliyense nyengo ndi ofanana. Izo zikuwoneka ngati izi: U = U1 + U2 + U3 + ... + UN ..

Ngati mfundo onse zapangika kugwirizana yomweyi resistors chikugwirizana mwachindunji ku malo a kasupe mphamvu, ndi voteji aliyense resistances adzakhala wofanana ndi voteji kuti amapanga gwero lokha: U1 + U2 + U3 + ... + UN = U ..

Mbali ina ya mankhwala a resistors kufanana kugwirizana dera ndi magetsi. Iwo anagawira kudzera m'nthambi za n'zosiyana molingana ndi kulimbikira kwa zigawo izi. M'mawu ena, wamkulu kulimbikira, chindichepere panopa, ndipo Tikawonetsetsa apamwamba pano, m'munsi kukana. Limeneli ndi lamulo loyamba Ohm akuti: I = U / R.

Panopa chokwanira mwa mfundo ndi Uwerenge mfundo ziliri pa nthambi iliyonse payokha. Ndipotu milandu sangathe kudziunjikira mu mfundo, kotero tisaiwale choyamba lamulo Kirchhoff a, lomwe limati: ". Gwero la mafunde, amene amakhala mu mfundo ndi wofanana Uwerenge mafunde akutuluka izo" Tikhoza kunena mosavuta - Uwerenge mafunde pa mfundo ndi ziro. Ndipo olembedwa akuti ali motere: "Ndalama za mafunde ndi wofanana ndi ziro."

Pano ndi malamulo zogwirizana dera popanda inductance ndi capacitance. Ngati kugwirizana yomweyi resistors ndi dera lomwelo ndi koyilo kapena capacitor, m'pofunika kupeza chifukwa cha impedance zinthu zonse. Kuti tichite zimenezi, kuwerengera inductance ndi capacitance.
