Zvinowanzoonekwa kuti vazhinji vanotanga vari kukanda pakupikisa pavanenge vachigadzirisa dunhu, uye rinobviswa uye rinosungirirwa.Kutaura zvazviri, yakagadziridzwa zvikuru.Chero bedzi iwe uchinzwisisa kukuvadza maitiro ekupikisa, haufanirwe kupedza nguva yakawanda.
Resistance ndiyo yakanyanya kuwanda mumidziyo yemagetsi, asi haisi iyo chikamu chine yakanyanya kukuvadza mwero.Vhura dunhu ndiyo yakajairika rudzi rwekupikisa kukanganisa.Kashoma kuti kukosha kwekupikisa kunowedzera, uye kukosha kwekupikisa kunova kuduku.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 ndeyekuti chiyero chekukuvadzwa kwekushomeka kwakaderera (pasi pe100Ω) uye kupikisa kwakanyanya (pamusoro pe100kΩ) kwakakwira, uye kukosha kwepakati (senge mazana emaohm kusvika makumi emakumi ekiroohms) 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 zvikatsva, 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 fuse resistor yapera, chimedu cheganda chinopeperetswa pane dzimwe nzvimbo, uye zvimwe zvacho hazvina kana makwara, asi hazvimbotsva kana kuita dema.Zvinoenderana nehunhu huri pamusoro, iwe unogona kutarisa pakutarisa kupikisa uye nekukurumidza kuwana iyo yakakuvadzwa kuramba.
Zvinoenderana nehunhu hwakanyorwa pamusoro, isu tinogona kutanga tacherekedza kana iyo yakaderera-inopikisa resistors pabhodhi redunhu yakapisa mavanga matema, uye zvino zvinoenderana nehunhu huzhinji hwevadzivisi vakavhurika kana kushorwa kunova kwakakura uye yakakwirira-inopikisa resistors. zviri nyore kukuvara.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 kusati kwaratidzwa Mukupedzisa, nekuti panogona kunge paine parallel capacitive elements mudunhu, pane kubhadharisa uye kuburitsa nzira), kana kupikisa kwakayerwa kudiki pane kupikisa kwezita, kunowanzo furatirwa.Nenzira iyi, kupikisa kwega kwega pabhodhi redunhu kunoyerwa zvakare, uye kunyange kana chiuru chimwe "chikauraiwa zvisina kunaka", mumwe haazorasikirwi.
