E aʻo pū i nā laʻana o nā resistors parallel a me nā laʻana o nā resistors series.
Mea Pale Kū'ē Moʻo
Inā hoʻopili ʻia nā resistors e like me ka mea i hōʻike ʻia ma ke kiʻikuhi ma luna, ua hoʻopili ʻia lākou ma ke ʻano series. Hiki i nā resistors i nīnau ʻia ke lilo i mau ʻāpana resistor, nā kukui, a i ʻole nā mea hana hoʻokaʻawale uila ʻē aʻe.
He paʻa ka hoʻouku uila (Q) i hiki ai i ka hoʻouku uila e neʻe ana ma ke kūʻē 1 (R 1 ) = ka hoʻouku uila e neʻe ana ma ke kūʻē 2 (R 2 ) = ka hoʻouku uila e neʻe ana ma ke kūʻē 3 (R 3 ). ʻO ke au uila (I) ka hoʻouku uila e kahe ana i loko o kekahi manawa (I = Q/t), no laila ke au uila e hele ana ma ke kūʻē 1 (I 1 ) = ke au uila e hele ana ma ke kūʻē 2 (I 2 ) = ke au uila e hele ana ma ke kūʻē 3 (I 3 ). Ma ke ʻano makemakika, ʻo ka huina o ke au uila (I) = I 1 = I 2 = I 3.
Ma ka ʻaoʻao ʻē aʻe, emi iho ka uila uila (V) i ka wā e neʻe ai ka uku uila ma o kēlā me kēia kū'ē. ʻO ka uila uila, i kapa ʻia hoʻi ʻo ka ʻokoʻa hiki uila, ʻo ia ka ikehu hiki uila no kēlā me kēia anakahi o ka uku uila. emi iho ka uila uila no ka mea ua hoʻohana ʻia ka ikehu uila i kēlā me kēia kū'ē uila. No laila, ua like ka huina uila uila (V) me ka huina o nā uila uila ma kēlā me kēia kū'ē. Ma ke ʻano makemakika, ʻo ka huina uila uila (V) = V1 + V2 + V3 . V = IR i hiki ai i ka huina uila uila V = IR1 + IR2 + IR3 . Ua like ke au uila e kahe ana i kēlā me kēia kū'ē no laila ua loli kēia kaulike i V = I (R1 + R2 + R3 ).
Ma muli o ke kaulike ma luna, ua hoʻoholo ʻia ʻo ka huina o ke kūʻē uila (R) a i ʻole ke kūʻē pani o ke kūʻē uila i hoʻopili ʻia ma ke ʻano he moʻo ua like ia me ka huina o kēlā me kēia kūʻē uila, ma ke ʻano makemakika R = R1 + R2 + R3 . Inā ʻelua wale nō resistors i hoʻopili ʻia ma ke ʻano he moʻo, ʻo ka waiwai resistor pani (R) = R1 + R2 . Inā ʻehā mau resistors i hoʻopili ʻia ma ke ʻano he moʻo, ʻo ka waiwai resistor pani (R) = R1 + R2 + R3 + R4 . Pēlā nō, inā he ʻelima a ʻoi aku paha ma mua o ʻelima mau resistors i hoʻopili ʻia ma ke ʻano he moʻo.
Laʻana o ka pilikia resistor series:
1. Hāʻawi ʻia ʻo R 1 = 2 Ω, R 2 = 3 Ω a me R 3 = 4 Ω. Hoʻopili ʻia nā resistor ʻekolu ma ke ʻano he moʻo. He aha ka waiwai o ke resistor pani? (Ω = Ohm).
Pahana
R = R1 + R2 + R3 = 2 + 3 + 4 = 9 Ω.
Hōʻike kēia hopena ua ʻoi aku ka nui o ke kū'ē pani ma mua o ke kū'ē o kēlā me kēia resistor i hoʻopili ʻia ma ke ʻano he moʻo.
2. Ua hoʻopili ʻia ʻelua mau resistors R 1 = 50 Ω a me R 2 = 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 e hele ana ma kēlā me kēia resistor.
Pahana
(a) R = R 1 + R 2 = 50 Ω + 50 Ω = 100 Ω.
(b) I = V / R = 12 Volts / 100 Ω = 0,12 Ampere
