Kodi pakali pano ndi yotani?

Zinthu zamakono zamakono (mabatire ndi mabatire) zimakhazikika kwambiri m'miyoyo yathu, kukhala chinthu chodziwikiratu ndi chachilengedwe kuti ambiri mwa eni awo samatha kuwerenga zomwe zinalembedwa pa mapepala ndi phukusi. Ndipo ndizachabechabe, chifukwa pali chenjezo lofunika kwambiri - "Usatseke." Aliyense amene akudziwa bwino zofunikira zamakono zamagetsi, amadziwa bwino lomwe zomwe zilipo pakali pano komanso chifukwa chake nkosavuta kuchepetsa oyendetsa.

Chitsime chilichonse chamakono chili ndi mitengo iwiri: zabwino ndi zoipa (+ ndi -) zenizeni zenizeni, komanso gawo ndi nthaka (zero, misa, nthawi zina gawo lina) kuti musinthe panopa. Kuyenda kwapadera kwapadera kungatheke kokha ngati mitengoyi ikugwirizana ndi zinthu zoyendetsa. Ngati chipangizo chogwiritsira ntchito magetsi chikugwirizanitsa ndi kupuma kwa otsogolera, ndiye kuti ntchito inayake idzachitidwa pakali pano kudutsa maulendo a chipangizocho. Chinthu chachikulu ndi chakuti maulendo a chipangizo ichi sagonjetsa ma electron kuti awadutse mosavuta, motero nthawi zonse tingaganize kuti pali kukana (kutsegula) kuchepetsa kuthamanga kwa magawo omwe alipo.

Kuti tipeze kumvetsetsa, timapereka chitsanzo cha madzi akuyenda kudzera mu kanjira (woyendetsa). Chiyambi cha kuyendayenda ndi mthunzi umodzi, ndipo mapeto ake ndi mthunzi wachiwiri. Pakati pa msewuwo muli magalasi a mphero ( madzi ), otembenuka ndi kayendetsedwe ka madzi (panopa). N'zachidziwikiratu kuti kuthamanga kwazitali nthawi zonse kumakhala kochepa chifukwa cha kukana kwa masamba. Koma chimachitika ndi chiyani ngati mphero ikutha? Madzi, osagonjetsedwa, amayenderera pamsewu pamtunda wothamanga umene gwero lingapereke (dera). Panthawi imodzimodziyo, kuthekera kwa chiwonongeko cha chisokonezo cha magwero ndi njirayo ndipamwamba kwambiri. Mu magetsi, mphamvu ya kuthamanga ndi mphamvu yamakono yamakono .

Chinthu chomwecho chikuchitika mu magetsi. Ngati, pa chifukwa china chilichonse, kutsutsana kwa dera kumayamba kukhala ndi zero, pakali pano panthawi yamphindi. Wophunzitsayo amatha kutenthedwa, ndipo magwero amasiku ano akuwonongeka. Njirayi yowonjezera magetsi ndi yowopsa ndipo imafuna kuthetsa mwamsanga. Kawirikawiri, woyenda dera amalowa mu dera, akuswa dera ngati atapeza nthawi yayitali. Mwa kufanana ndi madzi: njirayo imatsekedwa ndipo kutuluka kumatayika. Ndi mphamvu yotsekedwa, zimakhala zosavuta kudziŵa kuti mwapang'onopang'ono pali gawo lalifupi loyendetsa magetsi . Pachifukwa ichi, kusiyana kwa pakati pa mfundo zomwe zimagwiritsidwa ntchito ndi ma probes zimayesedwa ndi chipangizo chapadera (multimeter). Njira yosalunjikayo ikugwiritsidwa ntchito pogwiritsa ntchito chizindikiro kapena kupitiriza: ngati zidziwika kuti sipangakhale phulusa pazowonjezereka mwachindunji, ndiye yang'anani chikhalidwe ichi. Mu maginito amphamvu, izi ndi zomveka kuposa kuyesa kutsutsana kwenikweni kwa multimeter.

Mwa njira, ndicho chifukwa chake simungathe kugwirizanitsa matabwa a mabatire. Ngakhale kuti mphamvu zawo sizikwanira kuwononga kondomuyo, koma zigawo zamkati zomwe zimakhala mkati zimakhala zochepetsetsa mofulumira, kuchepetsa moyo wazinthu zonse.

Pogwiritsa ntchito chitetezo cha magetsi, mawu akuti "kuthamanga kwafupipafupi" nthawi zambiri amagwiritsidwa ntchito. Icho chimapangitsa mtengo wapatali wa kuwoneka kwawoneka ngati zotsatira za zochitika zaifupi. Pogwiritsa ntchito maulendo amtundu wamakono, mtengo wake wochulukirapo udzafikira patatha hafu (0.01 s pafupipafupi 50 Hz).

Tiyenera kuzindikira kuti pali magetsi apadera omwe maulendo afupikitsidwe sakhala ovuta, koma oyenera. Chitsanzo chochititsa chidwi - makina okwezeretsa, omwe arc yowoneka ndi yangwiro chabe.
