Pehea ku omaka resistors nā pōpō mau palapu?

Mea pale mū holapū - kekahi o ka walaʻauʻana kumu o ka uila kaapuni a i ka ikaika a ee iaaanu aey mea pale mū holapū a me ka lawelawe 'ana i ka hoohuli uila pono i loko o ke anakahi uila (a Hope versa), i ke omo o ka uila a me ka hana nui'ē aʻe hana. Kēia OE hehee ai mea he integral hapa o kekahi mea. No laila, manaʻo 'oe makemake e he inā pilikia ka haumāna electrician paha e ke aloha o ka uilaʻoe, mea pono ia oe a me ka omaka resistors ka hahau ana waihoʻoluʻu a me alphanumeric inoa no ka mea hoʻohālike o ka' ano o ka mea okoa eiiiiiaiou.

Inoa o resistors ma na kiʻikuhi i

Ma ka manaʻo o ka pou manao ona mea pale mū holapū ua denoted like me ka rectangle, a ua kau ma luna o ka palapala o ka Roma Hawaiʻi R. Ma hope o ka hōʻailona o ka pūkaʻina helu, ma i hiki ke loaʻa ka hehee ai i loko o ka hoakaka. Ke hoʻoholo 'ia ka huakai kaapuni inoa' ia paha o nā helu e hōʻike i ka palena iki e kū'ē'ē mai. Penei, he palapala R12 100 e manao i ka mea pale mū holapū 12 Ua hoonoho ia 100 ohms.

An nui ano o na kumu mua o kā lākou kākoʻo. Ignoring i kēia koho, e holo i ka pilikia o ke poho i ka pau noaia, a hiki ina i hana pololei 'ia o ka wehewehena o resistors ka lepili. Ke kiʻikuhi e e hōʻike:

• Roma numerals HEN, mai 1 a hiki i 5 watts;
• papamoe e hoomaemae ia ma ka waiwai o 0.5 watts;
• hoʻokahi aʻelua kēlā laina ma ka mana o ke 0,25 Watts a me 0,125 pakahi.

"*" Hoailona ua kau ma hope o ka pūkaʻina helu o kekahi mau resistors. Ua o ia hoʻi, i ka hoakaka ma luna o nā He kokekau wale wale. Na mau Hawaiʻi 'oe, e pono eʻohi mai ma luna o lākou iho.

Alphanumeric inoa

Alphanumeric omaka ano o na kumu o Soviet-i? Iecaianoaaiiuo, e like me kekahi ao-ka papa me nā huahana. Peni resistors i laweia mai, a wahi lulu huahana i hoʻomaka me he aka, a me ka hōʻailona. Ma keia hihia na huahelu i hoʻokohu 'ia penei:

• ka hōʻailona "E" a «R» mai nei i ka palena iki cia i hoike ma ohms;
• leka "M" hai mai ai ia ia'ku ua olelo ia i loko o megohms;
• kakauinoa "K" i complemented e pau ka laulā nā loina i hoike ma ka kiloomah.

Inā ka hōʻailona 'ōili mai ma hope o ka helu, ua kaheaia na loina a pau i loko o ka huahelu (33E = 33 ohms). E kuhikuhi i ka mahele palapala oweliweli huahelu (K55 = 0,55 kilohms = 550 ohms). Inā i ka hoailona o ka mahele, ka resistivity hōʻike like helu aiee me ka fractional hapa (1M3 = 1,3 megohms).

Denomination waihoʻoluʻu

Ka lōʻihi o kekahi o ka "ia'ku" He wale he mau millimeters. Pili a me ka ike i ka palapala, a nui ma keia hehee ai mea e hiki. No ka hoʻohālike o kēia mau eiiiiiaiou ua hoʻohana 'omaka resistors nā pōpō kaula. Ka mua mau auka e paa ai, he mau kuleana no ka denomination. Kekahi poʻe ma luna o ka pali holehole mai ai i manaʻo:

• i loko o ka 3- a 4-Lane kaʻaʻai kolu o ka pākī Ho'ākāka 'multiplier, a me ka ha - i ka pololei;
• 5-ala designations kolu o kala Hōʻike ka denomination, i ka hā - ka multiplier, a me ka lima - pololei;
• ono o Lane Hōʻike ka mahana kaʻi lau waiwai o ia'ku ai ka halepaahao pono, ina pūhaka o na mea e ae.

Ke kala hookolokolo Hōʻike ka laulā nā loina häʻawi mai ai iä ia. E hana me keia papaʻaina, e kōkua resistors omaka ma kēlā me kēia aka hoʻopili like i ka kekahi ololi, a me ka huahelu. No ka laʻana, ua loaʻa i ka mea pale mū holapū me ka ulaula, omaomao, eleele a me ka uliuli kaula. Decipher ke ano, ua ike i ke alo o ka mea pale mū holapū o 25 ohms * 10 = 250 ohms pololei o 25%.

kaʻina holehole mai ai i

Pehea e hooholo aʻaoʻao e hoʻomaka omńkalakala i? Ma hope o ka lepili resistors nā pōpō ka hahau hiki ke decoded i loko o nāʻaoʻao. E pale ka hilahila ma keia, ia mea e pono ke hoomanao i kekahi ano rula:

1. Inā he mea wale ekolu poe hao wale, ka mea mua, e mau e kai piha kokoke i ka lihi ma mua o ka mea hope.
2. Ke 4-ala oihana mua o ka heluhelu ao ao e e hooponoponoia ia mea, ma ke kala, a gula kala like 'ole - ka mea, e mau ana e ke aupuni' kokoke i ka hopena.
3. Ma nā hihia, ka mea pono e heluhelu ai i ka loaa i ke kumukuai o ka palena iki moʻo. Ināʻaʻole, he mea pono e decipher i kekahiʻaoʻao.

A hookaawale hihia o ka wahi o kaʻeleʻele jumper ma luna o ke kino. Ua o ia hoʻi, i ka hehee ai i ole ia'ku, a ua hoʻohana 'ia me ka jumper. Ano, ia oe i ike pehea e heluhelu i ka omaka resistors nā pōpō ka hahau ana, a me ka pilikia a me ka ho'ākāka 'ana o ka palena iki hehee ai oe eʻaʻole i.
