'O ka hopena kūpa'a - nā mea kākau

'O nā ku'iku'a he mau hi'ona o nā'ōpili'eneke e kū'ē i ka ho'oholo'ana o ka mana elee. Ho'ohana'ia lākou i nā ka'a kalaika a pau, a ma nā papa ha'awina. Hoomaopopo resistors ma na kēia mau hiʻona: mana ma ka palena iki ia'ku o ka papa o ka pololei Of manao, etc. Ma keia 'atikala, mākou e noonoo ia i kekahi mea i kū'ē'ē waiwai.. He aha ia? Ma lalo o ka denomination o ka ia'ku hehee ai pela, me ka nui waiwai o na ia'ku o ka hooholo ia ana o ka pilaʻikena therethrough. Ka uila mea pale mū holapū waiwai ua denoted e Lakina palapala R. He mea ma'amau ke kākau i kēia kumukū'ai ma nā pū'ulu like'ole Ohm. Ua loa'a kēia inoa i kona inoa no ka mahalo'ana i ke kākena Gelemānia kaulana'o Georg Simon Ohm, i'ike'ia no kāna'oihana ma ka papahana o ke a'o'ana i ka'oihana eletise. He aha e pono ai, e ike i ka waiwai o ka resistors? He aha ke koho pono o nā'enewai no ka papahana i koho'ia ai'ole koho i kahi analog no ka ho'oponopono'ana i nā meahana.

E no'ono'o i nā'ano o ka ho'opa'a'ana i nā kumu waiwai kūpono o nā pale i ke kumu o nā'enewa. 'Ekolu ala o ka hō'ailona hō'emi: digital - nā helu wale nō; Hō'ailona - ua ho'ohui'ia, me nā huahelu he mau leka kekahi; A,'o ka hopena, ka'oni - he hō'ailona o nā pale keka o nā lepe like'ole, ua like ka helu o nā hui, mai 3 a 5.

Ma hope a'e, e ho'olālā mākou i ke'ano o ka ho'opa'a'ana i ka waiwai o ka resistor, ma muli o ke'ano o nā mea. 'O nā'ano ho'oikaika ikaika o ke kelepona pēlē'ia ke'ano o ka pahu bale. Ho'ohālikelike'ia kēia mau mea i nā'ano'ekolu. Ho'ohana'ia nā'ōnaeho'ōpili wale no nā pale e loa'a'ole ka nui o ka waiwai no 999 ohms. E like me kēia: 2.0; 220; 750. E like me: 2 Ohm, 220 Ohm a 750 Ohm. Next i hoʻopaʻa 'iaʻano hoʻohana he comma palapala o ka Roma Hawaiʻi: R - mea he pa alima; K kilo, oia hoi, 1000; M - mega, 'o ia ho'i 1000000. Hiki ke ho'ololi'ia me kēia'ano o ka ho'opa'a'ana, i mea e loa'a ai ka waiwai o ka kū'ē, pono e ho'onui'ia ke kumukū'ai ma ka nui o ka leka. He hō'ailona o ia'ano mo'olelo: 220 R - 220 Ohm; 3K2 - mean 3200 Ohm; 1M1 -'o ia ho'i, 1100 kΩ.

Ho'opili'ia ka coding o nā mea i koho'ia ma ka'ao'ao o ke kino o ke kino. I nā hakakā o ka Soviet, ua ho'ohana'ia ke kahakai me ka ho'ololi'ana i kekahi'ao'ao,'o ia ka mea i'ike'ia ka ho'omaka'ana o ka helu koho. Ma nā'enehana hou,'o ka pahu pale pale hope loa he gula a he kālā paha, a'o ia ho'i ka papa hana kūpa'a (5 a 10 mau hapa). Inā loa'a ke kahakai he'ekolu wale nō lālā,'o ka papa hana pololei kūpono he 20 pakeneka. 'O ka ho'opili'ana,'o ia ho'i'o 3-4 mau pauna, ma nā papa mua'elua e loa'a ana ka waiwai o ka waiwai koho, a'o ke kolu - ka waiwai o ka mea ho'olaha. 'O ka ho'opā'ālua o 5-6 mau lālani i loko o nā mea'ekolu i loko o ka waiwai o ka mea i koho'ia, a ma ka hāhā - ka waiwai o ka mea ho'olaha.

'O ke'ano o ke kū'ē'ana i kēia manawa,'o ia ke kū'ē i ka pu'upu'u a i'ole ke kū'ē kū'ē SMD. Ma ia mau resistors omaka ka laulā a me ka symbolic. Ho'omaopopo wale'ia ia: ma ka māka mo'omeheka,'o nā huahelu mua e hō'ike i ka waiwai o ka inoa, a'o ka hope hope e hō'ike i ka heluna o nā zeros; I ka hō'ailona -'o nā helu'elua mua e hō'ike ana i ka inoa, a'o ka helu hope e hō'ike i ka waiwai o ka mea ho'olaha.

I ka ee iaaanu aey mea pale mū holapū , ka mea maʻamau i hoʻopaʻa 'ana o ka palena iki cia hoʻohana' ana i ka helu a me ka palapala o ka Lakina Hawaiʻi.
