Yadda tsaye alama resistors canza launin ratsi?

Resistor - daya daga cikin muhimman abubuwa na wani lantarki kewaye wanda yana da m ko m resistor da kuma hidima ga maida lantarki halin yanzu a cikin wani irin ƙarfin lantarki (ko mataimakin versa), da sha da wutar lantarki da kuma yin wasu ayyukan. Wannan m kashi ne wani ɓangare daga wani na'urar. Saboda haka tunanin kana da wani gogaggen lantarki ko kawai a lover of lantarki, shi ne amfani a gare ku, kuma alama resistors ratsi launi da kuma alphanumeric nadi ga kwatanta halaye na daban-daban aka gyara.

Nadi na resistors a cikin zane-zane

A kan manufar lantarki na'urorin resistor aka denoted matsayin murabba'i mai dari, wanda aka sanya a saman da wasika na Latin haruffa R. Bayan wata alama ce shi ne wani serial number, da abin da rabi za a iya samu a cikin jaddadawa. Kammala da kewaye nadi sa na lambobin da cewa nuna maras muhimmanci juriya. Saboda haka, wani rubutu R12 100 zai nufin cewa resistor 12 an saita zuwa 100 ohms.

An muhimmanci halayyar da abubuwa ne da iya aiki. Kyalewa wannan zabin, ka gudu da hadarin lalacewar dukan makirci, ko idan da definition resistors lakabtawa da aka yi daidai. Zane-zanen zai iya gano:

• Roman numerals jere daga 1 zuwa 5 watts.
• a kwance tsiri a wani darajar 0.5 watts.
• daya ko biyu QFontDatabase Lines a ikon 0.25 Watts da 0,125 bi da bi.

"*" Sign aka sanya bayan da serial number na wasu resistors. Yana nufin cewa sama da bayani dalla-dalla ne kawai m. A daidai dabi'u za ka bukatar ka karba a kan nasu.

Alphanumeric nadi

Alphanumeric alama halayyar da abubuwa na Soviet samarwa, kazalika da wasu duniya-aji kayayyakin. Sa alama resistors shigo da m kayayyakin iya fara a matsayin wani adadi da kuma wata alama ce. A wannan yanayin da raka'a kaddamarda kamar haka:

• alama ce "E" ko «R» ce da maras muhimmanci darajar da aka bayyana a ohms.
• harafin "M" ta gaya mana cewa juriya da aka bayyana a cikin megohms.
• hannu "K" an complemented duk lamba dabi'u da aka bayyana a kiloomah.

Idan alama ce bayyana bayan da lambobi, duk da dabi'u aka bayyana a cikin dukan raka'a (33E = 33 ohms). Don gane da sulusi da murabba'i harafi matsayi lambobi (K55 = 0,55 kilohms = 550 ohms). Idan ãyã daga hannun jari, da resistivity bayyana a matsayin lamba dabi'u da fractional part (1M3 = 1.3 megohms).

denomination launi

A tsawon wasu daga cikin "adawa" ne kawai 'yan millimeters. Aiwatar da kuma ganin haruffa da lambobi a kan wannan kashi ne da ba zai yiwu. Domin a kwatanta wadannan aka gyara aka yi amfani da alama resistors canza launin ratsi. A farko biyu makada ne ko da yaushe da alhakin denomination. Wasu a kan banki tube da ma'anar:

• a cikin 3- ko 4-rariya markings uku dash ma'anar multiplier, ta huɗu kuma - daidaito;
• 5-hanyar zane-zane da na uku launi nuna denomination, na huɗu - da multiplier, kuma na biyar - daidaito;
• shida rariya nuna zafin jiki coefficient na juriya , ko da wani cell AMINCI, idan thicker fiye da wasu.

Launi mashaya nuna lamba dabi'u sanya musu. Magance wannan tebur za ta taimaka resistors alama inda kowane inuwa yayi dace da wani factor, ko adadi. Alal misali, muna da resistor tare da ja, kore, launin ruwan kasa da kuma blue ratsi. Decipher da ma'anar, mun san cewa muna fuskantar wani resistor na 25 ohms * 10 = 250 ohms daidaito na 25%.

jerin tube

Yadda za a tantance abin da gefen don fara dikodi mai? Bayan lakabtawa resistors canza launin ratsi za a iya decoded a duka kwatance. Don kauce wa rikice a cikin wannan, wajibi ne a tuna da wasu sauki sharudda:

1. Idan akwai kawai uku makada, da farko za yaushe a located kusa da gefen fiye da na karshe.
2. The 4-hanyar abubuwa na karatu shugabanci ya kamata a ƙaddara da azurfa ko zinariya launi - za su ko da yaushe a located kusa da ƙarshen.
3. A wasu lokuta, dole ne a karanta ta yadda za a samu darajar da maras muhimmanci jerin. Idan ba haka ba, shi wajibi ne don decipher na wancan gefe.

A raba hali ne wuri na mai baki jumper a jiki. Yana nufin cewa, kashi na ba juriya da kuma ake amfani da matsayin jumper. Yanzu da ka san yadda za ka karanta alama resistors canza launin ratsi, da kuma matsalolin da definition da maras muhimmanci kashi za ka ba da.
