Sei anopomerwa chokuguma resistors mavara mitsetse?

Resistor - mumwe zvinokosha ane zvemagetsi redunhu iro rine dzose kana shanduka resistor uye anoshanda kutendeutsa Magetsi kuva voltage (kana vakutarisire), kuti Absorção de Água dzemagetsi uye kuita mamwe mabasa mazhinji. Ichi pusa chaikosha chinhu chinokosha chipi mudziyo. Saka funga uri ane ruzivo magetsi kana chete unoda zvemagetsi, unobatsira iwe uye chokuguma resistors mavanga ruvara uye alphanumeric nan'anuro fananidzo zvechadenga akasiyana zvinoriumba.

Pakunzi resistors vari chati

On pfungwa magetsi mano resistor runotaurwa somunhu rectangle, iyo anoiswa pamusoro tsamba Latin arufabheti R. Pashure chiratidzo chinhu Serial nhamba, ayo chinhu chinogona kuwanikwa Specification. Rinopedzisa redunhu rokuti yakatarwa nhamba kuti anoratidza aizviti nemishonga. Saka, chinyorwa R12 100 zvinoreva kuti resistor 12 yakaiswa kuti 100 ohms.

An chinokosha chakanangana okunze ndiko kugona kwavo. Kurega kuita izvi, iwe kumhanya pangozi kukuvadzwa zano rose, kunyange kana tsanangudzo resistors Kunyora Kwaiitirwa nemazvo. Madhayagiramu achaparadzwa ringazivikanwa:

• Mukuverenga kwechiRoma kubvira 1 kusvika 5 watts or;
• chinjikira Pfekenura ari kukosha 0.5 watts or;
• imwe kana mbiri mitsetse oblique panguva simba 0.25 Watts uye 0,125 azvaitwa.

"*" Sign anoiswa mushure Serial nhamba yevamwe resistors. Zvinoreva kuti apa nokurondedzerwa ndivo chete anofungidzirwa. Chaiwo netsika unofanira atore pachavo.

Alphanumeric izita

Alphanumeric chokuguma cho zvezvidzidzo kugadzirwa Soviet, uyewo vamwe zvigadzirwa nyika-kirasi. Chichatara resistors kupinza uye mudzimba zvigadzirwa anogona kutanga sezvo munhu uye chiratidzo. Panyaya iyi zviumbu akasarudzwa sezvinotevera:

• chiratidzo "E" kana «R» anoti aizviti ukoshi anoratidzwa ohms;
• tsamba "M" anotiudza kuti kurwisa runoratidzwa megohms;
• kusaina "K" vari nechimwe ose kusanganiswa tsika anotaurwa kiloomah.

Kana chiratidzo rinowanika mushure nhamba, vose tsika anotaurwa yose dzakabatana (33E = 33 ohms). Kuziva chikamu chiduku tsamba pozi digits (K55 = 0.55 kilohms = 550 ohms). Kana chiratidzo migove, ari resistivity akaratidza sezvo integer tsika ane fractional chikamu (1M3 = 1,3 megohms).

sangano ruvara

Kureba mamwe "Kusaurayiwa" ndiyo millimeters mashoma. Shandisa uye ona mavara uye nhamba iri maatomu akafanana izvi hazvibviri. Nokuti kuenzanisa yenhengo izvi rinoshandiswa chokuguma resistors mitsetse chitsvuku. mapoka maviri okutanga nguva dzose mhosva sangano. Vamwe pamahombekombe rinoparadza vane zvaanoreva:

• muna 3- kana 4-mukoto nyora rechitatu nokuputsanya rinorondedzera multiplier, uye wechina - kururama;
• 5-nzira Mironga ruvara yechitatu inoratidza sangano, wechina - the multiplier, uye wechishanu - yakarurama;
• rechitanhatu mukoto inoratidza tembiricha coefficient kurwisa kana foni kuvimbika, kana mukobvu kupfuura vamwe.

Color bhaa inoratidza nhamba tsika basa navo. Kukurira tafura iyi ichabatsira resistors chokuguma apo mumvuri nerimwe unoenderana imwe chinhu, kana nhamba. Somuenzaniso, tine resistor ane tsvuku, girini, mashava uye zvitema mitsetse. Decipher zvinoreva, tinoziva kuti tiri kutarisana resistor 25 ohms * 10 = 250 ohms rakarurama 25%.

kutevedzana rinoparadza

How yokusarudza divi kutanga decoding? Pashure Kunyora resistors kurohwa mavara inogona decoded zvose kumativi. Kudzivisa kuvhiringidzika mune ichi, zvinokosha kuyeuka zvimwe mitemo nyore:

1. Kana pane mapoka matatu chete, wokutanga nguva dzose uchava raiva pedyo kumucheto pane wokupedzisira.
2. The 4-nzira zvemamiriro pakuverenga mirayiridzo anofanira pakutsvaga sirivha kana yendarama ruvara - vachagarova raiva pedyo kuguma.
3. Mune zvimwe zviitiko, inofanira kuverenga sezvo kuwana kukosha aizviti akatevedzana. Kana kwete, zvakakodzera decipher mhiri.

A yoga nyaya ndiyo nzvimbo ane jumper nhema muviri. Zvinoreva kuti chinhu haana nemishonga uye rinoshandiswa senzira jumper. Zvino kuti munoziva kuti kuverenga kupenda resistors mavara mitsetse, uye matambudziko tsanangudzo aizviti chinhu hamungambovi.
