Iyo inopesana ndeyechikamu chemagetsi chemagetsi chinogadzira kuramba mukuyerera kwemagetsi zvazvino. Munenge dzese magetsi network uye matunhu emagetsi anowanikwa. Kupokana kunoyerwa muOhms. A ohm ndiko kupokana kunoitika kana iripo yeiyo ampere inopfuura nepanopokana neyakaopedza kurira kwematare ayo. Iyo yazvino inoenderana neiyo voltage pane iyo terminal magumo. Iyi ratio inomiririrwa naMutemo waOm:

Resistors anoshandiswa kune zvakawanda zvinangwa. Mienzaniso mishoma inosanganisira delimit yemagetsi zvemagetsi, chizvarwa chinopisa, kufanana uye kufananidza uye kutakura matunhu, kudzora kuwana, uye kugadzirisa nguva constant. Ivo vanowanika zviripo pamwe nekupokana tsika pamusoro pemhando dzinopfuura kupfuura mapfumbamwe ehukuru. Vanogona kushandiswa seyemagetsi mabhureki kuti vasiye kinetic simba kubva kuzvitima, kana kuva vashoma pane mashirimu emamirioni.

Kudzivirira Maitiro (Anodiwa Akanaka)
Muma1980s kuwedzera kugadzirwa kwevafesi kwakagadzira kukosha kwekurwisa kwakarasika tsika. Rudzi rwezvemhando dzekuramba dzakarongeka pamwe zvakadaidzwa zvakadaidzwa. Iwo maitiro anodiwa anotsanangurwa muE-Series. Mune e-akateerana, kukosha kwese kune imwe chikamu chakakwirira kupfuura zvakapfuura. Yakasiyana-siyana e-akatevedzana zviripo kune akasiyana mashinga.

Kudzivisa Zvikumbiro
Iko kune kusiyanisa kukuru muminda yezvekushandisa kune resistors; kubva pazvinhu zvakanyanyisa mumifananidzo yemagetsi emagetsi, kusvika mhindu yekuyera kwehuwandu hwemuviri. Muchitsauko chino zvakati wandei zvinoshandiswa zvinoshandiswa zvakanyorwa.

Resistors muhurukuro uye zvakafanana
Mumatunhu emagetsi, resitors dzinowanzove dzakabatana muhurukuro kana kufanana. Dunhu redunhu rinogona semuenzaniso rinosanganisira dzinoverengeka dzinokonzerwa nezviyero zvakajairika (e-series) kusvika pane chaiyo yekudzivisa kukosha. Zvekutevedzana, iyo yazvino kuburikidza neyavo mumwe nemumwe phamba yakafanana uye kupokana kwakaenzana kwakaenzana nehuwandu hwevanhu vanozorora. Kubatana kwakafanana, voltage kuburikidza neyavo mumwe nemumwe phamba zvakafanana, uye izvo zvinopesana nekukanganiswa zvakaenzana zvakaenzana nehuwandu hwehuwandu hwezvakashata zvevaridzike. Muzvinyorwa zvinotsauka mukufananidza uye nhevedzano tsananguro yakadzama yemienzaniso yekuverenga inopiwa. Kugadzirisa kunyange zvakanyanya kuomarara network, mitemo yeKirchhoff's Mitemo inogona kushandiswa.

Kuyera magetsi emagetsi (shunt uproor)
Magetsi zvazvino anogona kuverengerwa nekuyera voltage kudonha pamusoro pehunyanzvi hwekudzivisa neanozivikanwa kuramba, izvo zvakabatana mukutenderera nedunhu. Izvo zvazvino zvinoverengerwa nekushandisa mutemo weOHM. Iyi inonzi ambeter kana sunter inodziya. Kazhinji iyi ndiyo yakakwirira chaiyo manganin inopesana neyakaderera kuramba kukosha.

Resistors yeLDS
LED Mwenje inoda chaiyo yazvino kushanda kushanda. Akaderera kwazvo aripo haazovhenekera yakatungamirwa, nepo yakanyanya kukwirira mari inogona kupisa chishandiso. Naizvozvo, ivo vanowanzobatana mune zvakatevedzana nevanozorora. Izvi zvinonzi Ballast Resistors uye Pasinei nekutonga zvazvino mudunhu.

Mune mota iyo mhepo yekuvira kwemhepo inoitwa neiyo fan inofambiswa neye blower mota. Upano hwakakosha hunoshandiswa kudzora kumhanya kwe fan. Izvi zvinonzi iyo blower mota inodziya. Zvigadzirwa zvakasiyana zviri kushandiswa. Imwe dhizaini yakateedzana kweiyo yakasiyana saizi Wirewound vesistors kune imwe neimwe yekukurumidza kumhanya. Imwe dhizaini inosanganisira dunhu rakanyatsobatanidzwa pane bhodhi redunhu rakadhindwa.
