Kodi magetsi angadziwike bwanji ndikuyesedwa?

Mu dera lamagetsi, pali zigawo zambiri zosiyana ndi zinthu zosiyanasiyana zomwe ziyenera kuyesedwa. Zida zina zomwe zimatha kuyeza zinthu zosiyanasiyanazi zidzakhala zenizeni pa muyeso umodzi, koma zambiri zimaphatikiza miyeso kukhala chida chimodzi. Zomwe muyenera kuyeza ndi:

Panopa

Panopa ndikuyenda kwa magetsi ndipo amayezedwa mu ma amperes (amps, A). Chipangizo chomwe chimatha kuyeza panopa chimadziwika kuti "ammeter". Kuti muyese zamakono, chipangizo choyezera chiyenera kulumikizidwa motsatizana ndi dera kuti ma electron adutse pa ammeter pa mlingo womwewo pamene akudutsa dera.Zamakono zimatha kukhala zolunjika komanso zosinthika (zokhazikika kapena zosinthika). Izi zikukhudzana ndi momwe ma elekitironi amayendera mozungulira, mwina mwachindunji; mbali imodzi; kapena kusintha; kumangosinthasintha.

Kusiyana komwe kungatheke (voltage)

Voltage ndi kusiyana komwe kungathe pakati pa mfundo ziwiri mu dera ndipo zimaperekedwa ndi zomwe timatcha gwero la mphamvu mu dera; batri kapena socket ya khoma (magetsi amagetsi). Kuti muyese voteji, muyenera kulumikiza chipangizo chotchedwa voltmeter mofanana ndi dera.

Kutsutsana

Kukaniza kumayesedwa mu ma ohms (ohms) ndipo kumagwirizana ndi momwe zinthu za kondakitala zimaloleza kuti madzi azidutsamo. Mwachitsanzo, chingwe chachifupi chimakhala ndi mphamvu zochepa kuposa chingwe chachitali chifukwa zinthu zochepa zimadutsamo. Chipangizo chomwe chimatha kuyeza kukana chimatchedwa ohmmeter.

Pakalipano, kukana ndi kusiyana komwe kungatheke

Pali mgwirizano pakati pa ma volts, ma amps ndi ma ohms mumayendedwe amagetsi. Izi zimadziwika kuti lamulo la Ohm, loyimiridwa ndi makona atatu pomwe V ndi voltage, R ndi kukana, ndipo ine ndipano. Equation ya ubalewu ndi: amps x ohms = volts. Kotero ngati muli ndi miyeso iwiri, mudzatha kuwerengera inayo.

Magetsi

Mphamvu imayesedwa mu watts (W). M'mawu amagetsi, watt ndi ntchito yomwe imachitika pamene ampere imodzi ikuyenda kudzera mu volt imodzi.

Polarity

Polarity ndi kalozera wa mfundo zabwino ndi zoipa mu dera. Mwaukadaulo, polarity imapezeka m'mabwalo a DC, koma popeza mains (AC) ali ndi waya umodzi wokhazikika, izi zimapanga ma terminals otentha (amoyo) komanso osalowerera ndale pamasoketi ndi zolumikizira, zomwe zitha kuganiziridwa ngati polarity. Monga lamulo, polarity imasonyezedwa pazinthu zambiri (mwachitsanzo mabatire), koma zingakhale zofunikira kuyang'ana polarity pazida zina, monga oyankhula, pamene zalumphidwa.Chifukwa kuzindikira polarity kungaphatikizepo kusiyanitsa pakati pa zabwino ndi zoipa, ndi kutentha ndi ndale, pali zida zingapo zosiyanasiyana zomwe zingayang'ane izi, kuphatikiza zowunikira ma voltage ndi ma multimeter.

kupitiriza

Kupitilira ndi kuyesa kwa dera kuti muwone ngati ikugwira ntchito kapena ayi. Kuyesa kopitilira kukuwonetsa ngati magetsi amatha kudutsa chinthu chomwe chikuyesedwa kapena ngati dera lathyoka mwanjira ina.

mphamvu

Kuthekera ndi kuthekera kwa selo kusunga charge ndipo amayezedwa mu farad (F) kapena microfarad (µF). Capacitor ndi gawo lomwe limawonjezeredwa kudera kuti lisungidwe.

pafupipafupi

Mafupipafupi amapezeka m'mabwalo a AC ndipo amayezedwa mu hertz (Hz). Frequency ndi kuchuluka kwa ma oscillation a alternating current. Izi zikutanthawuza kuti ndi kangati komwe komweko kumasintha mayendedwe pa nthawi ya unit.
