Iyo resistor inhengo yemagetsi inongoita kuti igadzire kuramba mukuyerera kwemagetsi emagetsi. Munenge mune ese magetsi network uye emagetsi maseketi vanogona kuwanikwa. Kuramba kunopimwa nemaohms. An ohm ndiko kuramba kunoitika kana ikozvino yeimwe ampere inopfuura nepainopikisa ine vhoti imwe chete inodonha pamaterminal ayo. Ikozvino inoenderana nevoltage pamagumo ekupedzisira. Reshiyo iyi inomiririrwa neMutemo waOm:

Resistors inoshandiswa kune zvakawanda zvinangwa. Mienzaniso mishomanana inosanganisira delimit electric current, voltage division, heat generation, matching and loading circuits, control gain, uye fix time constants. Iwo anowanikwa mune zvekutengeserana ane maitiro ekupikisa pamusoro pehuwandu hunodarika mapfumbamwe emirairo yehukuru. Anogona kushandiswa semabhureki emagetsi ekubvisa simba rekinetic kubva muzvitima, kana kuva diki pane sikweya millimeter yemagetsi.

Resistor Values ​​(Inodiwa tsika)
Muma1950 kuwedzera kwekugadzirwa kwevanopikisa kwakagadzira kudiwa kwemaitiro ekupikisa. Huwandu hwemhando dzekupikisa hunomisikidzwa neanodaidzwa kuti anofarira kukosha. Hunhu hunodiwa hunotsanangurwa muE-series. Mune E-series, kukosha kwega kwega imwe muzana yepamusoro kupfuura yekare. Yakasiyana E-yakatevedzana iripo kune kwakasiyana kushivirira.

Resistor zvikumbiro
Pane mutsauko wakakura muminda yemashandisirwo evanopikisa; kubva kuzvinhu chaizvo mumagetsi edhijitari, kusvika midziyo yekuyera yehuwandu hwemuviri. Muchitsauko chino maapplication akawanda anozivikanwa akanyorwa.

Resistors munhevedzano uye parallel
Mumaseketi emagetsi, resistors anowanzo kubatanidzwa munhevedzano kana mukufanana. Mugadziri wedunhu anogona semuenzaniso kusanganisa akati wandei anopikisa neakajairwa kukosha (E-series) kuti asvike kune chaiyo yekupikisa kukosha. Kune akatevedzana yekubatanidza, iyo yazvino kuburikidza yega yega resistor yakafanana uye yakaenzana kuramba yakaenzana nehuwandu hweanopikisa ega. Nekubatana kwakafanana, iyo voltage kuburikidza neresitorendi yega yega yakafanana, uye inverse yeyakaenzana kuramba yakaenzana nehuwandu hwehupikisi hwehupikisi kune ese anoenderana resistors. Muzvinyorwa zvinopikisa mune parallel uye nhevedzano tsananguro yakadzama yemienzaniso yekuverenga inopihwa. Kugadzirisa zvakatonyanya kuoma network, Kirchhoff's redunhu mitemo inogona kushandiswa.

Kuyera magetsi ikozvino (shunt resistor)
Magetsi azvino anogona kuverengerwa nekuyera kudonha kwevoltage pamusoro peiyo chaiyo resistor ine inozivikanwa inopikisa, iyo yakabatana munhevedzano nedunhu. Ikozvino inotarwa nekushandisa mutemo weOhm. Iyi inonzi ammeter kana shunt resistor. Kazhinji iyi ndeye yakakwira chaiyo manganin resistor ine yakaderera kupikisa kukosha.

Resistors ye LEDs
Mwenje ye LED inoda chaiyo ikozvino kuti ishande. Yakanyanya kuderera ikozvino haibatise iyo LED, nepo yakawandisa ikozvino inogona kupisa mudziyo. Nokudaro, ivo vanowanzobatanidzwa munhevedzano nevanopikisa. Izvi zvinodaidzwa kuti ballast resistors uye zvingori kudzora ikozvino mudunhu.

Blower mota resistor
Mumotokari mhepo inofefetera inofambiswa nefeni inofambiswa neinofuridza mota. Yakakosha resistor inoshandiswa kudzora kumhanya kwe fan. Izvi zvinonzi blower motor resistor. Magadzirirwo akasiyana ari kushandiswa. Imwe dhizaini inoteedzana akasiyana saizi wirewound resistors kune yega fan kumhanya. Imwe dhizaini inobatanidza dunhu rakanyatsobatanidzwa pane rakadhindwa redunhu bhodhi.
