ʻAtikala e pili ana i nā Resistors ma ke ʻano like
Inā ua hoʻopili ʻia nā resistors e like me ke kiʻi, ua hoʻopili ʻia nā resistors ma ke ʻano like.
ʻO ke au uila (au uila = ka uku uila e kahe ana i loko o kahi manawa pōkole) e komo ana i ke kiko hui like me ke au uila e puka ana mai ke kiko hui. Aia kekahi mau hui ʻana i hiki ai i ka huina o ke au uila = ka nui o ke au uila e kahe ana i kēlā me kēia hui. Ma ke ʻano makemakika, I = I 1 + I 2 + I 3. ʻOiai like ka ʻokoʻa hiki ke uila a i ʻole ka volta uila i kēlā me kēia hui.
I = V/R no laila e loli ana ke kaulike ma luna nei i I = V/R1 + V/R2 + V/R3 . Ua like ke ana uila, no laila e loli ana kēia kaulike i I = V (1/R1 + 1/R2 + 1/ R3 ). Inā ʻo ke kū'ē like he 1/R a laila ʻo I = V (1/R). No laila, 1/R = 1/R1 + 1/R2 + 1/ R3.
Loaʻa i nā kaapuni like ka pono, inā haki ke au uila i kekahi o nā resistors, e hoʻomau ke kahe ʻana o ke au uila i nā resistors ʻē aʻe. ʻOiai ma ke ʻano moʻo, inā haki ke au uila i loko o kekahi resistor, a laila ʻaʻole e uila ʻia nā resistors āpau.
Laʻana pilikia 1:
Ua ʻike ʻia ʻo R 1 = 2 Ω, R 2 = 3 Ω. Ua like nā resistor ʻelua. He aha ka waiwai o ke resistor like? (Ω = Ohm).
pāʻoihana:
1/R = 1/R 1 + 1/R 2 = 1/2 + 1/3 = 3/6 + 2/6 = 5/6
R = 6/5 = 1.2 Ω.
Hōʻike kēia hopena ua liʻiliʻi ka waiwai o ke kū'ē like ma mua o ka waiwai o kēlā me kēia kū'ē like.
Laʻana pilikia 2:
Ua hoʻopili ʻia ʻelua mau resistors R 1 = 50 Ω a me 50 ma ke ʻano series a me ke ʻano parallel, i hoʻopili ʻia i kahi pākahiko 12 Volt. E hoʻoholo:
(a) Ke kū'ē like
(b) Ke au uila ma o kēlā me kēia resistor
pāʻoihana:
(a) Nā mea kū'ē i ka mo'o:
R = R 1 + R 2 = 50 Ω + 50 Ω = 100 Ω.
Nā mea kū'ē i ke ʻano like:
1/R = 1/R 1 + 1/R 2 = 1/50 + 1/50 Ω = 2/50
R = 50/2 = 25 Ω
(b) Nā mea pale ma ke ʻano moʻo:
ʻO I = V / R = 12 Volts / 100 Ω = 0.12 A
Nā mea kū'ē i ke ʻano like:
ʻO I = V / R = 12 Volts / 25 Ω = 0.48 A
Hōʻike kēia hopena he ʻoi aku ka nui o ke au uila holoʻokoʻa e kahe ana ma ke kaapuni like, ʻoiai he liʻiliʻi ka nui o ke au uila holoʻokoʻa e kahe ana ma ka moʻo.
