The resistor ukoshi - nzira yakarekodwa

Resistors - chinobatanidza dzemagetsi nematunhu ane kuramba kwemutemo Magetsi. Ivo zvinoshandiswa zvose magetsi nematunhu, kunyange kupfuura dzokutanga. Kusiyanisa resistors kubudikidza anotevera zvinhu: simba panguva aizviti kurwisa kwakaita mukirasi zvakarurama Of pfungwa, etc. Munyaya ino, tichakurukura chinhu chakadai nemishonga ukoshi.. Chii? Pasi sangano iri kurwisa chinhu zvinoreva chechetere ukoshi yomunyika kurwisa kuti chikamu Magetsi therethrough. The zvemagetsi resistor ukoshi runotaurwa ne Latin netsamba R. ukoshi Izvi kazhinji akanyorwa muzvikamu zvakadai, sezvo Om. chikwata ichi ainzi pashure yakakurumbira yefizikisi yokuGermany Georg Simon Ohm, anozivikanwa nokuda basa rake mumunda Magetsi. Zvaunofanira kuziva kukosha resistors? Chii waizosarudza zvakarurama zvinhu kuti zano chakagadzirirwa kunhonga chinhu analoginen pamusoro kugadziriswa mudziyo.

Funga kutsikisa nzira chezita kurwisa tsika pamusoro redzimba zvinhu. Pane nzira nhatu chiratidzo resistors: Digital - zvinosanganisira chete nhamba; hunhu - ari zvabatanidzwa pamwe chete nhamba uye tsamba varipo; uye pakupedzisira ruvara - idungwerungwe transverse mapoka mavara akasiyana, nhamba Lanes yakasiyana, kubva 3 kusvika 5.

Uyezve ongorora hwakanyorwa resistor mutengo zvichienderana norudzi maatomu akafanana. Constant nemishonga waya-mhando zvinhu zviri cylindrical dhiramu. Wairatidza kwakadaro zvinhu zvose zvitatu. Digital kutsikisa chete kushandiswa resistors, kukosha aizviti ukoshi asingasvavi pfuura 999 ohms. Zvinoita sezvinotevera: 2.0; 220; 750. Means azvaitwa 2 ohms, 220 ohms uye 750 ohms. Next kutsikisa mhando anoshandisa koma mabhii earufabheti Latin: R - ari chikwata; K - a churu, kureva 1000; M - Mega, kureva 1000000. Zvakaratidza kuti iri kurekodha nzira, kuti ndiwane resistor kukosha anofanira kuva Numeric ukoshi kane kukosha chairoiro. Muenzaniso wakadaro chinyorwa 220 R - 220 ohms zvinoreva; 3K2 - zvinoreva 3200 ohms; 1M1 - zvinoreva 1100 ohms.

Color Coding of yavose sezvavakatarirwa ukoshi rinoshandisirwa mhiri kurekodha nhengo muviri cylindrical. The resistors Soviet-akaita chokuguma rakaiswa ane zvaizopedza kune rimwe divi, inoratidza rakatanga decoding. Mazuva zvinhu okupedzisira bhendi nguva dzose goridhe kana sirivha bhaa code, uye zvinoreva kurwisa yakarurama kirasi (5 kana 10 muzana). Kuri kuti kupenda chinosanganisira mapoka matatu chete, kuti default kushivirira kirasi chinorehwa 20 muzana. Encoding ine 3-4 zvisungo mukukosha maviri okutanga unotora munhu chezita kukosha, uye wechitatu - kukosha multiplier. Encoding pakati 5-6 zvisungo rokutanga matatu ukoshi unotora yacho aizviti, uye wechina - kukosha multiplier.

Next maonero nemishonga - munhu Chip resistor kana SMD-resistor. In dzakadaro resistors chokuguma riri Numeric uye kwokufananidzira. Iye chete anomira: iri digitaalinen wokupemberera digits okutanga anoratidza chezita kukosha, uye yokupedzisira nenhamba zeros; mu hunhu - the digits maviri okutanga anoratidza nesangano, uye yokupedzisira hunhu - kukosha multiplier.

In iri shanduka resistor , mureza zvokurekodhwa aizviti ukoshi kushandisa nhamba uye tsamba muchiLatin arufabheti.
