Nhanganyaya kuResistor Color Codes
Munyika yezvemagetsi, ma resistors anomira sechimwe chezvinhu zvakakosha uye zvinoshandiswa zvakanyanya. Anoita basa rakakosha mukudzora magetsi, kupatsanura ma voltage, uye kudzivirira zvikamu zvinonzwa zvedunhu nekuderedza kukwira kwemagetsi. Kune chero ani zvake anoshanda mune zvemagetsi - vangave vanofarira zvemitambo, vadzidzi, kana nyanzvi - kunzwisisa kodhi yemavara e resistor kwakakosha. Chinyorwa chino chichakuzivisai nezvema resistor color codes, zvichikubatsirai kuona ma resistor values zvakarurama uye zvinobudirira.
Chii chinonzi Resistor Color Codes?
Makodhi emavara eResistor imhando dzakasiyana dzemabhandi ane mavara akapendwa pamuviri weresistor. Mavara aya anomiririra manhamba uye anoshandiswa kuona kukosha kweresistor, kushivirira, uye dzimwe nguva kuvimbika kana kukundikana kweresistor. Mabhandi emavara anobatsira kukunda dambudziko rekudhinda manhamba madiki pachimiro chidiki checylindrical cheresistor.
Mitemo Yepasi Pose
Mwero unonyanya kushandiswa wekodhi dzemavara pazvinodzivirira ndiyo mwero weElectronic Industries Association (EIA). Mwero uyu unopa nzira inogamuchirwa nevanhu vose inotangira kuma1920. Mumakore apfuura, wakaita kuti kutaurirana kwakanaka uye kwakarongeka pakati pevagadziri, vagadziri, uye mainjiniya vanoita zvemagetsi kuve nyore.
Sei Uchifanira Kushandisa Makodhi Emavara?
Ma resistors paakatanga kushandiswa, miviri yawo yaive midiki zvekuti haikwanise kuratidza kukosha kwe resistance kwakadhindwa. Kuisa mavara emhando kwaive mhinduro itsva kudambudziko iri. Kuisa mavara muchimiro chemavara kune zvakanakira zvakawanda:
1. Kushanda zvakanaka kwenzvimbo: Zvidziviriro zvidiki hazvigone kugamuchira mavara akadhindwa, asi zvinogona kunyorwa nemavara.
2. Kuziva zviri nyore: Kana zvanzwisiswa, makodhi emavara anobvumira kuverenga nekukurumidza ma resistor values pasina zvimwe zvishandiso.
3. Kugara kwenguva refu: Mavara haaperi nyore nyore sezvinoita mavara akadhindwa, zvichiita kuti zvive nyore kuverenga kwenguva refu.
Chati yeKodhi yeRuvara
Chati yekodhi yemavara eresistor ine mavara gumi, anomiririra nhamba 0–9, uye mamwe mavara anoratidza kushivirira, kuvimbika, uye dzimwe nguva coefficient yekupisa. Ngationgororei hurongwa hwekutanga hwekodhi yemavara:
| Ruvara | Kukosha kweDigital | Zviwanziri | Kushivirira |
|——-|————-|———|———–|
| Nhema | 0 | 10^0 | – |
| Bhurawuni | 1 | 10^1 | ±1% |
| Tsvuku | 2 | 10^2 | ±2% |
| Orenji| 3 | 10^3 | – |
| Yero| 4 | 10^4 | – |
| Girini | 5 | 10^5 | ±0.5% |
| Bhuruu | 6 | 10^6 | ±0.25% |
| Violet | 7 | 10^7 | ±0.1% |
| Gireyi | 8 | 10^8 | ±0.05% |
| Muchena | 9 | 10^9 | – |
Mabhendi ekushivirira anosanganisirawo:
– Goridhe: ± 5%
– Sirivha: ± 10%
- Hapana bhendi: ± 20%
Makodhi Emavara Ekudzivirira Kuverenga
Kunyora mavara eResistor kunowanzo sanganisira mabhendi mana, mashanu, kana matanhatu. Rimwe nerimwe rine nzira yakasiyana zvishoma yekuona kukosha.
Zvidziviriro zveMabhendi Mana:
1. Bhendi Rokutanga: Rinomiririra nhamba yekutanga inokosha.
2. Bhendi Rechipiri: Rinomiririra nhamba yechipiri inokosha.
3. Chidimbu Chechitatu: Chinowanza, zvichiratidza simba regumi (10^n).
4. Chidimbu chechina: Kushivirira kweresistor.
Muenzaniso: Kana resistor ine mavara mabhendi eBrown, Dema, Tsvuku, uye Goridhe:
– Bhendi Rokutanga (Brown) = 1
– Bhendi Rechipiri (Dema) = 0
– Bhendi rechitatu (Dzvuku) = 10^2 = 100
– Bhandi rechina (Goridhe) = ±5%
Kukosha kweKuramba: \(10 \kawa 100 = 1000 \Omega \) kana 1kΩ ine kutsungirira kwe±5%.
Zvidziviriro zveMabhendi Mashanu:
1. Bhendi Rokutanga: Nhamba yekutanga inokosha.
2. Bhendi Rechipiri: Nhamba yechipiri inokosha.
3. Bhendi rechitatu: Nhamba yechitatu inokosha.
4. Bhendi rechina: Kuwanda.
5. Bhendi rechishanu: Kushivirira.
Muenzaniso: Kana resistor ine mavara mabhendi Brown, Black, Black, Red, uye Brown:
– Bhendi Rokutanga (Brown) = 1
– Bhendi Rechipiri (Dema) = 0
– Bhandi rechitatu (Dema) = 0
– Bhendi rechina (Dzvuku) = 10^2 = 100
– Bhandi rechishanu (Brown) = ±1%
Kukosha kweKuramba: \(100 \kawa 100 = 10,000 \Omega \) kana 10kΩ ine kutsungirira kwe±1%.
Nyaya Yakakosha: Vadzivisi veMabhendi Matanhatu
Ma resistors ane mabhendi matanhatu anosanganisira bhendi rekuwedzera re coefficient yekupisa, chinhu chakakosha mukushandiswa kwakarurama uko kukosha kwekudzivirira kunogona kuchinja nekupisa.
1. Bhendi Rokutanga: Nhamba yekutanga inokosha.
2. Bhendi Rechipiri: Nhamba yechipiri inokosha.
3. Bhendi rechitatu: Nhamba yechitatu inokosha.
4. Bhendi rechina: Kuwanda.
5. Bhendi rechishanu: Kushivirira.
6. Chitsama chechitanhatu: Kuenzana kwekupisa (ppm/°C).
Muenzaniso: Kana uine mavara ane mavara matsvuku, matema, matema, matema, matema, matema, uye matema:
– Bhendi Rokutanga (Brown) = 1
– Bhendi Rechipiri (Girini) = 5
– Bhandi rechitatu (Dema) = 0
– Bhendi rechina (Dzvuku) = 10^2 = 100
– Bhandi rechishanu (Girini) = ±0.5%
– Bhandi rechitanhatu (Brown) = 100 ppm/°C
Kukosha kweKuramba: \(150 \kawa 100 = 15,000 \Omega \) kana 15kΩ ine kutsungirira kwe±0.5% uye temperature coefficient ye100 ppm/°C.
Maitiro Ekubata Nemusoro Makodhi Emavara eResistor
Imwe nzira inozivikanwa yekurangarira makodhi emavara e resistor yakarongwa ndeiyi:
“B kushaya B rown Tsvuku O range Y ellow Gireni reen B lue V iolet Gireni reruvara ruchena”
Kana, rwiyo rwekugadzira rwakaita se:
"Shiri Dzemhando Yepamusoro Dzokuyeukai Old Y ellow G oats Asi V iolet Goes W hite."
Izvi zvinobatsira kunyora kurongeka kwezviitiko nenzira isingakanganwiki, zvichiita kuti zvive nyore kurangarira.
mhedziso
Makodhi emavara eResistor mhinduro ine hungwaru uye inogara kwenguva refu kudambudziko rinoshanda rinotarisana neindasitiri yemagetsi. Kugona makodhi emavara kunopa simba kune chero munhu anoshanda nemaresistor, zvichimugonesa kuona kukosha kweresistance nemazvo uye zvinobudirira. Kunyangwe zvingaita sezvakaoma pakutanga, nekushandisa nekushandisa mnemonics, kududzira makodhi emavara eresistor kunova chinhu chechipiri. Sezvo tekinoroji ichifambira mberi, ruzivo rwekutanga rweresistor color coding runoramba rwuri hunyanzvi hwakakosha muzvishandiso zvemunofarira zvemagetsi kana nyanzvi.
