Ngā Āhuatanga o ngā Ara RLC
Ko te ara iahiko RLC he momo ara iahiko hiko kei roto ko te ātete (R), te inductor (L), me te capacitor (C) kua whakaritea kia raupapa, kia whakarara rānei. He maha ngā āhuatanga o tēnei ara iahiko e mea nui ai i roto i ngā tono hangarau hiko me te hangarau hiko. Ka matapakihia e tēnei tuhinga ngā āhuatanga o ngā ara iahiko RLC, mai i ngā kaupapa taketake ki ā rātou tono tūturu.
Te Māramatanga Taketake o ngā Ara RLC
E rua ngā momo matua o ngā ara iahiko RLC: Ngā Ara Iahiko Raupapa RLC me ngā Ara Iahiko Whakarara RLC.
1. Ara iahiko raupapa RLC: I tēnei ara iahiko, ka honoa raupapatia te ātete (R), te inductor (L), me te capacitor (C).
2. Ara iahiko whakarara RLC: I tēnei ara iahiko, ka honoa whakarara te ātete (R), te inductor (L), me te capacitor (C).
He rerekē ngā āhuatanga o ēnei momo ara iahiko e rua, engari e whakawhirinaki ana ki ngā mātāpono taketake o te haruru me te mana tauhohe.
Ngā Āhuatanga o ngā Ātete (R), ngā Inductors (L), me ngā Capacitors (C)
Hei mārama ki tētahi ara iahiko RLC, he mea nui kia mārama ki ngā āhuatanga o ia wāhanga:
1. Ātete (R): He wāhanga te ātete e aukati ana i te rere o te iahiko hiko, ā, e huri ana i te pūngao hiko hei wera. Ka inehia te ātete (R) i roto i ngā ohm (Ω).
2. Pūhiko (L): Ko te pūhiko he wāhanga e penapena ana i te pūngao i roto i te āhua o te papa aukume ina pā te iahiko hiko mā roto. Ka inehia te pūhiko (L) i roto i te henries (H).
3. Pūngao (C): Ko te pūngao he wāhanga e penapena ana i te pūngao i roto i te āhua o te papa hiko i waenganui i ngā pereti papatahi e rua. Ka inehia te pūngao (C) i roto i ngā farad (F).
Ngā Āhuatanga o ngā Whakaritenga Raupapa me ngā Whakaritenga Whakarara
Ara iahiko raupapa RLC
I roto i te ara iahiko RLC raupapa, ka honoa te ātete, te inductor, me te capacitor mai i te pito ki te pito, ka hanga he ara iahiko kotahi. Ko te hua o tēnei he iahiko kotahi e rere ana i roto i ngā wāhanga e toru, engari he rerekē ngā ngaohiko puta noa i ia wāhanga.
1. Āraitanga Katoa (Z): Ko te āraitanga he ine i te ātete katoa i roto i te ara iahiko AC, ā, i roto i te ara iahiko raupapa RLC ka tatauhia mā te:
\[
Z = \sqrt{R^2 + (X_L – X_C)^2}
\]
ko \(X_L = 2\pi f L\) te tauhohenga ā-whakauru, ā, ko \(X_C = \frac{1}{2\pi f C}\) te tauhohenga ā-pūmanawa.
2. Te Whakaohooho: Ka tae te ara iahiko raupapa RLC ki te whakaohooho ina \(X_L = X_C\) ina rānei \(2\pi f L = \frac{1}{2\pi f C}\), ko te auau whakaohooho (\(f_r\)) ko:
\[
f_r = \frac{1}{2\pi \sqrt{LC}}
\]
I te auau whakakorikori, ko te aukati katoa o te ara iahiko e whakawhirinaki ana ki te ātete anake, ā, ka puta te iahiko mōrahi.
3. Tauwehe Kounga (Q): Ka ine te tauwehe kounga (Q) i te whai huatanga o te ara iahiko ki te penapena pūngao. Mō te ara iahiko raupapa RLC, ka tatauhia te \(Q\) penei:
\[
Q = \frac{f_r L}{R}
\]
Ara Whakarara RLC
I roto i tētahi ara iahiko RLC whakarara, ka honoa ngā ātete, ngā ine hiko, me ngā pūnga i ō rātou pito, ka hangaia he ara maha mō te iahiko hiko.
1. Te Whakaurunga Katoa (Y): Ko te whakauru te whakamuri o te aukati, ā, i roto i te ara iahiko RLC whakarara ka tatauhia mā te:
\[
Y = \sqrt{G^2 + (B_L – B_C)^2}
\]
ko \(G = \frac{1}{R}\) te kawe hiko, ko \(B_L = \frac{1}{X_L}\) te whakapūmau i te hiko, ā, ko \(B_C = \frac{1}{X_C}\) te whakapūmau capacitive.
2. Te Whakaohooho: Pērā i te ara iahiko raupapa, ka tae hoki te ara iahiko RLC whakarara ki te whakaohooho ina rite te auau whakaohooho ki te \(B_L = B_C\), ina rānei ko tōna auau whakaohooho he rite ki:
\[
f_r = \frac{1}{2\pi \sqrt{LC}}
\]
I te auau whakakorikori, ko te iti rawa te whakaurunga katoa, ā, ko te iahiko katoa e whiwhihia ana e te ara iahiko ko te mōrahi.

2. Tauhohenga i runga ake i te auau oro: I runga ake i te auau oro, ka mahi te ara iahiko i runga i te āhua ā-whakaoho. I roto i te ara iahiko raupapa, ka arahina te iahiko e te ngaohiko, i roto ia i te ara iahiko whakarara, ka whakaroa te iahiko i te ngaohiko.
3. Tauhohenga i te Āhuatanga: I te auau āhuatanga, ka mahi ātete noa te ara iahiko, ā, kei te āhua ōrite te ngaohiko me te iahiko.
Tauwehenga Mana
I roto i te horopaki o te mana, ko te tauwehenga mana (PF) te ōwehenga o te mana hohe ki te mana katoa i roto i te ara iahiko. I te wā e pāorooro ana, ka tata te PF ki te 1, e tohu ana kua huri te nuinga o te mana hei mahi hohe. I waho o te pāorooro, he iti ake te PF nā te noho mai o te wāhanga mana tauhohe.
