ʻAtikala e pili ana i nā Resistors ma ke ʻano moʻo
Inā pili nā resistors e like me ka mea i hōʻike ʻia ma ke kiʻi, ua hoʻonohonoho ʻia nā resistors ma ke ʻano moʻo. Hiki i ke resistor a i ʻole ke kū'ē uila i nīnau ʻia ke ʻano o nā ʻāpana resistor, nā kukui, a i ʻole nā kū'ē uila ʻē aʻe.
Ke neʻe nei ka uku uila ma o ke kū'ē 1 (R1) = ka uku uila neʻe ma o ke kū'ē 2 (R2) = neʻe ka uku uila ma o ke kū'ē 3 (R3). Au uila ʻO (I) kahi uku uila e kahe ana i loko o kekahi manawa (I = Q / t), no laila ke au uila ma o ke kū'ē 1 (I1) = ke au uila ma o ke kū'ē 2 (I2) = ke au uila ma o ke kū'ē 3 (I3). Ma ke ʻano makemakika, ʻo ka huina o ke au uila (I) = I1 =I2 =I3.
I ka ʻaoʻao ʻē aʻe, emi iho ka uila uila (V) ke neʻe ka uku uila ma o kēlā me kēia resistor. ʻO ka uila uila i kapa ʻia hoʻi he ʻokoʻa hiki uila, he ikehu hiki uila no kēlā me kēia anakahi o ka uku uila. Hoʻemi ʻia ka uila uila no ka mea ua hoʻohana ʻia ka uila i kēlā me kēia kū'ē uila. No laila, ua like ka huina uila uila (V) me ka nui o ka uila i kēlā me kēia resistor. Ma ke ʻano makemakika, ʻo ka huina uila uila (V) = V1 +V2 +V3. V = IR no laila ʻo ke kaulike o ka uila uila ʻo V = IR1 + IR2 + IR3Ua like ke au uila e kahe ana ma kēlā me kēia resistor i hiki ai ke loli kēia kaulike i V = I (R1 + R2 + R3).
Ma muli o ka hoʻohālikelike ma luna, hiki ke hoʻoholo ʻia ʻo ke kū'ē uila holoʻokoʻa (R) a i ʻole ke kū'ē like o ke kū'ē uila
ʻo ka mea i hoʻopili ʻia ma ke ʻano he moʻo ua like ia me ka huina o kēlā me kēia kū'ē uila, ma ke ʻano makemakika R = R1 + R2 + R3Inā ʻelua wale nō resistors i loko o ka moʻo, ʻo ke resistor like (R) = R1 + R2Inā he ʻehā mau resistors i loko o ka moʻo, ʻo ke resistor like (R) = R1 + R2 + R3 + R4Pēlā nō, inā he ʻelima a ʻoi aku paha nā resistors ʻelima i hoʻopili ʻia ma ke ʻano moʻo.
Laʻana pilikia 1:
Inā ʻike ʻia, R 1 = 2 Ω, R 2 = 3 Ω a me R 3 = 4 Ω. Hoʻopili ʻia nā resistor ʻekolu ma ke ʻano series. He aha ka waiwai o ke resistor like? (Ω = Ohm ).
pāʻoihana:
R = R1 + R2 + R3 = 2 + 3 + 4 = 9 Ω.
Hōʻike kēia hopena ua ʻoi aku ka nui o ke kū'ē like ma mua o ka waiwai o nā resistors i hoʻopili ʻia ma ke ʻano series.
Laʻana pilikia 2:
Ua hoʻopili ʻia ʻelua mau resistors R 1 = 50 Ω a me 50 Ω ma ke ʻano series a ua 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) R = R 1 + R 2 = 50 Ω + 50 Ω = 100 Ω.
(b) I = V / R = 12 Volts / 100 Ω = 0.12 A
