Nhanganyaya kuResistor Color Codes
Pendauluan
Ma resistors ndeimwe yezvinhu zvakakosha uye zvakakosha mumagetsi. Basa rawo nderekudzivirira kufamba kwemagetsi mudunhu. Kuti tizive kukosha kwe resistor, tinowanzo shandisa kodhi yeruvara iri pamuviri we resistor. Iyi kodhi yeruvara yakakosha nekuti resistance haiwanzo kuratidzwa munhamba kana rugwaro pazvikamu zvidiki izvi. Chinyorwa chino chichakurukura tsananguro, nhoroondo, maitiro ekuverenga , uye kukosha kwemakodhi eruvara pa ma resistors.
Nhoroondo yeResistor Color Codes
Tisati tanzwisisa maverengerwo emakodhi emavara eresistor, zvinobatsira kutanga tanzwisisa nhoroondo yawo. Sisitimu yekodhi yemavara eresistor yakatanga kugadzwa neRadio Manufacturers Association (RMA) muma1920. Kubva ipapo, kushandiswa kwemakodhi emavara kuratidza kukosha kweresistance kwave kwakapararira uye kwakajairika. Magetsi emazuva ano achiri kushandisa sisitimu iyi zvakanyanya nekuda kwekushanda kwayo.
Kunzwisisa Makodhi Emavara Ekudzivirira
Kunyora mavara eResistor inzira yekunyora kukosha kweresistance uye tolerances uchishandisa mabhandi ane mavara akatenderedza muviri weresistor. Ruvara rwega rwega runomiririra nhamba chaiyo uye rune chirevo chaicho chinobatsira kuona resistor. MaResistor anowanzova nemabhandi ane mavara mana kusvika mashanu.
Maitiro Ekuverenga Makodhi Emavara eResistor
Pa resistor ine mavara mana, bhendi rega rega rine zvarinoreva. Kutevedzana kwekuverenga kunotanga kubva pabhendi rekutanga uye kunopera nekurongeka kwaro. Heino zvinoreva bhendi rega rega:
1. Bhendi rekutanga: Nhamba yekutanga yehukuru hwekupikisa.
2. Bhendi rechipiri: Nhamba yechipiri yehukuru hwekupikisa.
3. Chidimbu chechitatu: Chinowanza simba (chinowedzera simba rekudzivirira kaviri).
4. Chidimbu chechina: Kushivirira kweResistor.
Muzvirambidzo zvine mavara mashanu, kurongeka kwacho kwakafanana, asi nekuwedzera kwemufananidzo wechitatu unokosha:
1. Bhendi rekutanga: Nhamba yekutanga yehukuru hwekupikisa.
2. Bhendi rechipiri: Nhamba yechipiri yehukuru hwekupikisa.
3. Bhendi rechitatu: Nhamba yechitatu yehukuru hwekupikisa.
4. Chidimbu chechina: Chinopa simba rekuwedzera.
5. Bhendi rechishanu: Kushivirira kweResistor.
Heino tafura inoratidza kukosha kunomiririrwa neruvara rumwe nerumwe:
| Ruvara | Nhamba | Kuwanda | Kushivirira |
|————|——-|———————-|———|
| Nhema | 0 | 1 | – |
| Chokoreti | 1 | 10 | ±1% |
| Tsvuku | 2 | 100 | ±2% |
| Orenji | 3 | 1,000 | – |
| Yero | 4 | 10,000 | – |
| Girini | 5 | 100,000 | ± 0.5% |
| Bhuruu | 6 | 1,000,000 | ± 0.25% |
| Pepuru/Violet| 7 | 10,000,000 | ± 0.1% |
| Gireyi | 8 | 100,000,000 | ±0.05% |
| Muchena | 9 | 1,000,000,000 | – |
| Goridhe | – | 0.1 | ±5% |
| Sirivha | – | 0.01 | ±10% |
| Hapana | – | – | ±20% |
Muenzaniso weKuverenga Kodhi yeRuvara
Ngatitarisei muenzaniso wekuti tingaverenga sei kukosha kwekudzivirira zvichibva pane kodhi yemavara iripo:
Chinodzivirira chine Mabhendi mana
Semuenzaniso, ngatitii pane resistor ine kodhi yemavara tsvuku, tsvuku, tsvuku, uye goridhe. Heino maitiro ekuiverenga:
1. Ribhoni yekutanga (tsvuku) = 2
2. Ribhoni yechipiri (tsvuku) = 2
3. Bhandi rechitatu (tsvuku) = chinhu chinowanza 100
4. Bhandi rechina (goridhe) = kushivirira ±5%
Saka, kukosha kwekupikisa ndekwekuti:
\[ 22 \kawa 100 = 2200 \, \Omega \text{ or } 2.2 \, k\Omega \]
Nekushivirira kwe±5%.
Chinodzivirira Mabhendi Mashanu
Semuenzaniso, ngatitii pane resistor ine kodhi yeruvara rweyero, pepuru, tsvuku, brown, uye girini. Heino maitiro ekuiverenga:
1. Bhandi rekutanga (yero) = 4
2. Bhandi rechipiri (pepuru) = 7
3. Ribhoni yechitatu (tsvuku) = 2
4. Chidimbu chechina (brown) = chinowedzera nhamba 10
5. Bhandi rechishanu (girini) = kushivirira ±0.5%
Saka, kukosha kwekupikisa ndekwekuti:
\[ 472 \kawa 10 = 4720 \, \Omega \text{ or } 4.72 \, k\Omega \]
Nekushivirira kwe±0.5%.
Kukosha Kwekunzwisisa Makodhi Emavara eResistor
Kunzwisisa makodhi emavara e resistor hunyanzvi hwakakosha kune chero munhu anoshanda nemagetsi. Unyanzvi uhwu hunokubvumidza kuti:
1. Ziva Maitiro Ekudzivirira Kukurumidza: Haudi mamwe maturusi kuti uzive kukosha kwekudzivirira.
2. Kudzivisa Zvikanganiso MuCircuit: Kusarudza resistor value isiriyo kunogona kukonzera kuti circuit isashande zvakanaka kana kuti zvimwe zvikamu zvikanganiswe.
3. Wedzera Kubudirira: Nekugona uku, unogona kushanda zvinobudirira uye nekukurumidza paunenge uchibatanidza kana kugadzirisa maseketi emagetsi.
Mhedziso
Makodhi emavara eResistor inzira inoshanda zvikuru yekunyora kukosha kweresistance yezvikamu zvidiki izvi. Nekunzwisisa hwaro hwekuverenga makodhi emavara eresistor, unogona kuona nekukurumidza uye nemazvo kukosha kweresistance uye tolerances, zvichikubatsira kuunganidza nekuchengetedza maelectronic circuits zviri nani . Kunzwisisa kwakasimba kwemakodhi emavara eresistor kuchaita kuti uve nyanzvi ine hunyanzvi munyika yemagetsi.
Nechinyorwa chino, tinotarisira kuti wava kunzwisisa zviri nani nzira iyi uye unogona kuishandisa muhupenyu hwako hwezuva nezuva , kunyanya kana uchiwanzo shanda nemidziyo yemagetsi kana maseketi.
