Magetsi angaonekwa nekuongororwa sei?

Mudunhu remagetsi, kune zvakawanda zvakasiyana zvikamu uye zvinhu zvakasiyana zvinoda kuyerwa. Zvimwe zvezvishandiso zvinogona kuyera izvi zvakasiyana-siyana zvichange zvakanangana nechiyero chimwe chete, asi mazhinji achabatanidza kuyerwa kuita chinhu chimwe. Zvinhu zvekuyera zvinosanganisira:

Zviripo

Ikozvino kuyerera kwemagetsi uye inoyerwa neamperes (amps, A). Mudziyo unogona kuyera ikozvino unozivikanwa se "ammeter". Kuyera ikozvino, mudziyo wekuyera unofanirwa kubatanidzwa munhevedzano nedunhu kuitira kuti maerekitironi apfuure nepakati peammita pamwero wakafanana sezvaanopfuura nepadunhu.Ikozvino inogona kuva yakananga uye yakasiyana-siyana (nguva dzose kana yakasiyana). Izvi zvine chekuita nekuti maerekitironi anofamba sei nedunhu, kana zvakanangana; munzira imwe; kana kuchinjanisa; shure uye mberi.

Inogona kusiyana (voltage)

Voltage ndiyo inogona mutsauko pakati pemapoinzi maviri mudunhu uye inopihwa neyatinodaidza kuti simba remagetsi mudunhu; bhatiri kana socket yemadziro (mains magetsi). Kuyera voltage, unofanirwa kubatanidza mudziyo unonzi voltmeter uchienderana nedunhu.

Kurwisana

Resistance inoyerwa mu ohms (ohms) uye ine hukama nemabatiro anoita zvinhu zve conductor zvinobvumidza ikozvino kuyerera nemairi. Semuenzaniso, tambo pfupi ine kushomeka kushoma pane tambo refu nekuti zvinhu zvishoma zvinopfuura nepairi. Mudziyo unogona kuyera kuramba unonzi ohmmeter.

Ikozvino, kuramba uye zvinogona kusiyana

Pane hukama pakati pe volts, amps uye ohms mumagetsi emagetsi. Uyu unozivikanwa semutemo weOhm, unomiririrwa negonyonhatu uko V ari voltage, R kuramba, uye ini ndiri parizvino. Iyo equation yehukama uhu ndeye: amps x ohms = volts. Saka kana uine mativi maviri, uchakwanisa kuverenga imwe yacho.

Magetsi

Simba rinopimwa nemawati (W). Mumashoko emagetsi, watt ibasa rinoitwa kana imwe ampere ichiyerera kuburikidza nevolt imwe.

Polarity

Polarity ndiko kutaridzika kwezvakanaka uye zvisina kunaka mapoinzi mudunhu. Nehunyanzvi, polarity inongoitika mumaseketi eDC, asi sezvo mains (AC) iine waya imwe yakadzikwa, izvi zvinogadzira kupisa (mhenyu) uye nzvimbo dzisina kwazvakarerekera pamasoketi uye zvinongedzo, izvo zvinogona kufungidzirwa se polarity. Semitemo yakawanda, polarity inoratidzwa pazvinhu zvakawanda (semuenzaniso mabhatiri), asi zvingave zvakakosha kutarisa polarity pane mamwe maturusi, sematauri, paanenge asvetuka.Nekuti kuona polarity kunogona kusanganisira kusiyanisa pakati pezvakanaka nezvakaipa, uye kupisa uye kwazvakarerekera, kune akati wandei akasiyana maturusi anogona kutarisa izvi, kusanganisira magetsi ekuona uye multimeter.

kuenderera mberi

Kuenderera mberi ndiyo bvunzo yedunhu kuona kuti iri kushanda here kana kuti kwete. Muedzo wekuenderera mberi unoratidza kana magetsi achikwanisa kupfuura nepakati pechinhu chiri kuedzwa kana kuti dunhu rakaputsika neimwe nzira.

емкость

Capacitance kugona kwesero kuchengeta chaji uye inoyerwa nemafaradhi (F) kana microfarads (µF). A capacitor chikamu chinowedzerwa kune dunhu kuchengetedza charge.

frequency

Frequency inoitika mumaseketi eAC uye inoyerwa nehertz (Hz). Frequency ndiyo nhamba yekutenderera kweinochinjana ikozvino. Izvi zvinoreva kuti kangani iyo yazvino inoshandura kutungamira payuniti nguva.
