chifukwa bolodi dera wobiriwira?

Chifukwa chiyani matabwa ozungulira omwe ndawona onse ali obiriwira?Ma capacitors pamsika amasiyana kukula, kuyambira ang'onoang'ono mpaka akulu.Yaing'ono ngati njere ya mpunga, yaikulu ngati galasi lamadzi.
Ntchito ya ma capacitor, monga tonse tikudziwa, ndikusunga magetsi.Mwachiwonekere, kukula kwakukulu, mphamvu yaikulu, ndi yaying'ono, ndi yaying'ono.Koma anthu ambiri sadziwa kuti, kuwonjezera pa voliyumu, pali chinthu china chomwe chimatsimikizira mphamvu - kupirira mtengo wamagetsi.Zimatsimikizira kuchuluka kwa magetsi omwe capacitor angapirire.Chimodzimodzinso ndi mfundo ya voliyumu, mphamvu yokulirapo yomwe imalimbana nayo, mphamvu ya capacitor idzakhala yaikulu.
Koma m'miyoyo ya anthu ambiri, aliyense amakonda ma capacitor ang'onoang'ono pamene ma capacitors ali ndi ntchito yofanana.Koma mukaganizira mtengo wake, anthu ambiri amayenera kusankha yokulirapo.
Chifukwa chiyani ma board amagetsi amagetsi omwe ndawona onse ali obiriwira?
Nthawi yoyamba yomwe ndinawona bolodi lamagetsi lamagetsi, masewera omwe ndinkasewera ndili mwana anali opanda ntchito.Atatha kumasula, bolodi mkati mwake linali lobiriwira.Pamene ndinali kukula, ndinaona matabwa okulirakulirabe.Chidulecho chimapeza kuti ambiri amawoneka obiriwira.
Ndiye n'chifukwa chiyani bolodi wozungulira wobiriwira?Ndipotu silinena kuti likhale lobiriwira, koma ndi mtundu wotani umene wopanga akufuna kupanga.Gawo lalikulu la chifukwa chosankha matabwa ozungulira obiriwira ndikuti zobiriwira sizimakwiyitsa kwambiri maso.Pamene ogwira ntchito yopanga ndi kukonza nthawi zambiri amayang'ana matabwa ozungulira, zobiriwira sizingabweretse mavuto otopa mosavuta.
Ndipotu, anthu ambiri sadziwa kuti pali matabwa a buluu, ofiira, achikasu, ndi akuda.Mitundu yosiyanasiyana imapakidwa utoto pambuyo popanga.Ndi mtundu umodzi wa utoto, mtengowo udzachepetsedwa pang'ono.Panthawi yokonza, zimakhala zosavuta kusiyanitsa kusiyana ndi mtundu wakumbuyo.Mitundu ina si yosavuta kusiyanitsa.
Kodi mphete yamtundu pa resistor imatanthauza chiyani?
Aliyense amene waphunzirapo zasayansi amadziwa kuti resistors ali ndi mphete zambiri zamitundu ndipo ndi zokongola.Ndiye diso lamtundu pa resistor limatanthauza chiyani?Zotsutsa zomwe zimagwiritsidwa ntchito nthawi zambiri ndizitsulo za mphete zinayi ndi zisanu.Amagwiritsa ntchito mitundu yosiyanasiyana kuti agwirizane ndi manambala osiyanasiyana.Kuphatikiza manambala ogwirizana ndi mitundu yosiyanasiyana kumapanga mtengo wotsutsa wa resistor.Mitundu yomwe imawonetsedwa ndi mphete zamitundu ya zopinga ndi zofiirira, zakuda, zofiira, ndi golidi.Pakati pawo, bulauni imayimira 1, yakuda imayimira 0, yofiira imayimira 2, ndipo golide imayimira cholakwika cha chotsutsa, kusonyeza kuti kukana kwa resistor ndi 1KΩ.Ndiye bwanji osangosindikiza kukana mwachindunji pa resistor?Anthu ambiri sadziwa kuti chifukwa chimodzi cha izi ndikuti ndizosavuta kusamalira.Komabe, ndi chitukuko cha sayansi ndi luso lamakono, sizikudziwikabe ngati kukana kudzapitiriza kusiyanitsa mtundu wamtundu m'tsogolomu.
N'chifukwa chiyani pali soldering pafupifupi pamene soldering?
Kuwotcherera ndiye vuto lofala kwambiri pa soldering.Zikuoneka kuti welded pamodzi ndi zitsulo Mzere, koma si ophatikizidwa.Chifukwa chiyani mtundu uwu wa kuwotcherera kwenikweni umachitika?Pali zifukwa zotsatirazi: kukula kwa nugget ndi kochepa kwambiri kapena sikunafike pamlingo wosungunuka, koma kumangofika pamtundu wa pulasitiki, womwe umakhala wosakanikirana pambuyo pa kugubuduza.Malo osungunuka a solder ndi otsika, mphamvu siikulu, kuchuluka kwa malata omwe amagwiritsidwa ntchito mu soldering ndi ochepa kwambiri, malata a solder si abwino, ndi zina zotero.
