Zvinowanzoonekwa kuti vazhinji vanotanga vari kukanda pakupikisa pakugadzirisa dunhu, uye rinobviswa uye rinosungirirwa.Zvechokwadi, pane zvakawanda zvekugadzirisa.Chero bedzi iwe uchinzwisisa kukuvadza maitiro ekupikisa, haufanirwe kupedza nguva yakawanda.
Resistor ndiyo yakanyanya kuwanda mumidziyo yemagetsi, asi haisi iyo chikamu chine yakanyanya kukuvadza mwero.Vhura dunhu ndiyo yakajairika rudzi rwekupikisa kukanganisa.Kashoma kuti kushorwa kuve kukuru, uye kashoma kuti kushorwa kuve kudiki.Zvakajairika zvinosanganisira kabhoni film resistors, simbi film resistors, waya ronda resistors uye inishuwarenzi resistors.
Mhando mbiri dzekutanga dzekupikisa ndidzo dzinonyanya kushandiswa.Imwe yehunhu hwekukuvadzwa kwavo ndeyekukuvadza kwakanyanya kweyero yekushomeka (pasi pe100Ω) uye yakakwirira kuramba (pamusoro pe100kΩ), uye kupikisa kwepakati (senge mazana emaohm kusvika makumi emakiloohms) Kukuvadza kushoma;chechipiri, kana zvidziviriro zvakaderera zvakakuvadzwa, zvinowanzopiswa uye zvakasvibiswa, izvo zviri nyore kuwana, nepo zvinopikisa zvakanyanya zvisingawanzokuvadzwa.
Wirewound resistors anowanzo shandiswa kune yakakwira ikozvino kudzikisira, uye kuramba hakuna hombe.Kana cylindrical wire ronda resistors pazvinopiswa, mamwe anoshanduka kuita dema kana kuti pamusoro pacho pachaputika kana kutsemuka, uye mamwe anenge asina makwara.Cement resistors imhando yewaya maronda resistors, anogona kuputsika kana apiswa, zvikasadaro hapazovi nezvinooneka.Kana iyo fuse resistor ichipisa, chigamba cheganda chinoputika pamusoro, uye vamwe havana maronda, asi haambofi akapiswa kana kusviba.Zvinoenderana nehunhu huri pamusoro, iwe unogona kutarisa pakutarisa kupikisa uye nekukurumidza kuwana kukanganiswa kupikisa.
Zvinoenderana nehunhu hwakanyorwa pamusoro, tinogona kutanga tacherekedza kana iyo yakaderera-inopesana resistors padhiketi bhodhi ine chero maratidziro ekupisa matema, uyezve maererano nehunhu huzhinji hweanopikisa akavhurika kana kushorwa kunova kwakakura kana vanopikisa vari. yakakuvadzwa, uye yakakwirira-resistant resistors inokuvadzwa nyore.Isu tinogona kushandisa multimeter kuyera zvakananga kushorwa pamigumo yese yekumusoro-kupikisa resistor pabhodhi redunhu.Kana kuyerwa kupikiswa kwakakura kupfuura kupikisa kwezita, kushorwa kunofanirwa kukuvadzwa (ona kuti kushorwa kwakadzikama mushure mekunge chiratidziro chagadzikana. Mukupedzisa, nekuti panogona kunge paine parallel capacitive element mudunhu, pane yekuchaja uye yekuburitsa nzira. ), kana kuyerwa kupikiswa kuri kudiki pane kushomeka kwezita, kunowanzo furatirwa.Nenzira iyi, kupikisa kwega kwega pabhodhi redunhu kunoyerwa kamwe chete, kunyange kana chiuru chimwe "chikauraiwa zvisina kunaka", chimwe hachizoshaikwi.
