ʻAtikala e pili ana i ke code kala Resistor
ʻO ke kū'ē kekahi ʻāpana o kahi kaapuni uila e hana ana e kāohi i ka helu o nā au uila. Ma keʻano laulā, aia ʻelua ʻano o nā kū'ē, ʻo ia hoʻi nā kū'ē wili uea a me nā kū'ē kalapona. Hoʻohana pinepine ʻia nā kū'ē wili uea i loko o ka hale hana, i hana ʻia ma ke kāʻei ʻana i ka uea maikaʻi ma luna o ka ʻili o ka paipu insulator. Hoʻohana pinepine ʻia nā kū'ē kalapona i nā kaapuni uila, cylindrical, a he mau uea ma nā wēlau ʻelua. Hōʻike ʻia ka waiwai o ke kū'ē kalapona i loko o ke code kala a hōʻike ʻia ma ka ʻili o ke kū'ē.
Hiki ke ʻike ʻia ka waiwai kū'ē o kahi resistor ma ka wehewehe ʻana i ke code kala resistor. No ka hoʻomaopopo ʻana i kēia, e nānā mua i ka papa ma lalo nei, a laila e aʻo i ka pilikia hoʻohālike e hoʻoholo ai i ka waiwai kū'ē resistor.
Laʻana pilikia 1:
ʻO ke kumukūʻai kū'ē o ka resistor ma ke kiʻi he…
pāʻoihana:
Hōʻike nā kala mua ʻelua i nā helu mua ʻelua o ka waiwai kū'ē, hōʻike ke kala ʻekolu i ka mana ʻumi i hoʻohana ʻia no ka hoʻonui ʻana, a hōʻike ke kala ʻehā i ka hoʻomanawanui o ka ʻokoʻa.
ʻO ke kala mua = ʻulaʻula = 2
ʻO ka lua o ke kala = ʻalani = 3
ʻO ke kolu o ke kala = ʻeleʻele = 101 = 10
ʻO ke kala ʻehā = gula = 5%
ʻO ka waiwai o ke kū'ē he 230 Ω me kahi ʻokoʻa o 5% x 230 Ω = 11.5 Ω. Inā he loli o ka mahana, ʻo ke kū'ē liʻiliʻi loa he 230 11 - 11.5 Ω = 218.5 Ω a ʻo ke kū'ē kiʻekiʻe loa he 230 Ω + 11.5 Ω = 241.5 Ω.
Laʻana pilikia 2:
He aha ka waiwai o ke kū'ē'ē o ka resistor ma ke kiʻi?
pāʻoihana:
ʻO ke kala mua = ʻeleʻele = 1
ʻO ka lua o ke kala = ʻeleʻele = 0
ʻO ke kolu o ke kala = polū = 10 6 = 1000,000
ʻO ke kala ʻehā = gula = 5%
ʻO ke kumukūʻai o ke kūʻē he 10,000,000,000 me kahi ʻokoʻa o 5% x 10,000,000 Ω = 500,000 Ω. Inā he loli o ka mahana, ʻo ka palena iki loa he 10,000,000 500 - 500,000 Ω = 9,500,000 Ω a ʻo ka palena kiʻekiʻe loa he 10,000,000 Ω + 500,000 Ω = 10,500,000 Ω.
