Resistor chinhu chinoshandiswa pakugadzira resistance mukuyerera kwemagetsi. Munenge mune ese ma network emagetsi uye ma electronic circuits anowanikwa. Resistance inoyerwa mu ohms. Ohm i resistance inoitika kana current yeampere imwe inopfuura nepakati pe resistor ine volt imwe chete inodonha pama terminals ayo. Current inoenderana ne voltage kumativi ese eterminal. Iyi ratio inomiririrwa neMutemo waOhm:

Ma resistors anoshandiswa pazvinangwa zvakawanda. Mimwe mienzaniso inosanganisira kuganhurira magetsi emagetsi, kupatsanura magetsi, kugadzira kupisa, kufananidza nekurodha macircuits, kuwedzera simba rekutonga, uye kugadzirisa nguva. Anowanikwa mumusika ane resistance values ​​dzinopfuura mapoinzi mapfumbamwe. Anogona kushandiswa semabhureki emagetsi kubvisa simba remagetsi kubva muzvitima, kana kuti madiki pane square millimeter yemagetsi.

Maitiro eResistor (Maitiro anodiwa)
Mumakore ekuma1950, kugadzirwa kwakawanda kwezvinodzivirira kwakagadzira kudiwa kwezvinodzivirira zvakajairwa. Mhando dzezvinodzivirira dzakajairwa dzine zvinodaidzwa kuti zvinofarirwa. Zvinodzivirira zvakajairwa zvinotsanangurwa muE-series. MuE-series, kukosha kwese kwakakwira kupfuura kwekare. Mhando dzakasiyana dzeE-series dziripo dzezvinodzivirira zvakasiyana.

Zvishandiso zveResistor
Kune mutsauko mukuru muminda yekushandiswa kwe resistors; kubva kuzvinhu zvakanyatsonaka mumagetsi edhijitari, kusvika pamidziyo yekuyera yehuwandu hwemuviri. Muchitsauko chino mashandisirwo akawanda anozivikanwa akanyorwa.

Vadziviriri vakatevedzana uye vakafanana
Mumacircuit emagetsi, ma resistors anowanzo batanidzwa mu series kana parallel. Semuenzaniso, mugadziri wecircuit anogona kusanganisa ma resistors akati wandei ane standard values ​​(E-series) kuti asvike pa resistance value chaiyo. Pa series connection, current kuburikidza ne resistor yega yega yakafanana uye equal resistance yakaenzana nehuwandu hwe resistors yega yega. Pa parallel connection, voltage kuburikidza ne resistor yega yega yakafanana, uye inverse ye equal resistance yakaenzana nehuwandu hwe inverse values ​​dze all parallel resistors. Mu articles resistors in parallel and series, tsananguro yakadzama yemienzaniso yekuverenga inopiwa. Kugadzirisa network dzakaoma zvakanyanya, mitemo yecircuit yaKirchhoff inogona kushandiswa.

Pima magetsi emagetsi (shunt resistor)
Mwenje wemagetsi unogona kuverengwa nekuyera kudonha kwevoltage pamusoro pe resistor chaiyo ine resistor inozivikanwa, iyo yakabatana mumutsara necircuit. Mwenje unoverengwa uchishandisa mutemo weOhm. Uyu unonzi ammeter kana shunt resistor. Kazhinji uyu i resistor yemanganin chaiyo ine resistor yakaderera.

Zvidziviriro zve LED
Mwenje ye LED inoda magetsi chaiwo kuti ishande. Mwenje wakaderera haubatidzi LED, nepo magetsi akawandisa anogona kupisa mudziyo. Saka, anowanzobatanidzwa akatevedzana nema resistors. Aya anonzi ballast resistors uye anotonga magetsi ari mudunhu.

Chinodzivirira mota yeBlower
Mumota, sisitimu yekufema mweya inofambiswa nefeni inotyairwa nemota inofefetera. Chinodzivisa mhepo chinoshandiswa kudzora kumhanya kwefeni. Izvi zvinonzi chinodzivirira mhepo inofefetera. Magadzirirwo akasiyana ari kushandiswa. Dhizaini imwe imhando dzakasiyana dzezvinodzivirira mhepo zvine saizi dzakasiyana zvekukurumidza kwefeni yega yega. Imwe dhizaini inosanganisira dunhu rakabatanidzwa zvizere pabhodhi redunhu rakadhindwa.
