Ka matapakihia e tēnei tuhinga te tātai pūnga raupapa, tōna mātāpono mahi, me pēhea te tatau i te pūnga katoa, me ōna tono mahi.
Te Mārama ki ngā Pūnga me ā rātou Mātāpono Mahi
I mua i te kōrero mō ngā pūnga hiko raupapa, he mea nui kia mārama ki ngā kaupapa matua o ngā pūnga hiko. Ko te pūnga hiko he mea hanga mai i ngā ara iahiko e rua e wehea ana e te ara iahiko. Ina pāngia te pūnga hiko e te ngaohiko, ka kohikohi te utu hiko ki runga i ngā ara iahiko e rua he rerekē ngā polarities, ka hangaia he mara hiko i roto i te ara iahiko.
Ko te kaupapa matua o te pūnga ka whakaatuhia e te tātai:
\[ C = \frac{Q}{V} \]
kāore i te mana:
– Ko te capacitance i roto i ngā Farads (F) ko \( C \),
– Ko te utu i roto i te Coulomb (C) ko \( Q \),
– Ko te ngaohiko i roto i ngā Volts (V) ko \( V \).
Ngā Pūngao Raupapa
Ina honoa ngā pūnga iahiko i roto i te raupapa, ka tohaina te utu kotahi, engari ka wehea te ngaohiko e whakamahia ana i waenganui i a rātou. I roto i te ara iahiko pūnga iahiko raupapa, ko te ngaohiko katoa ko te tapeke o ngā ngaohiko takitahi e whakamahia ana ki ia pūnga iahiko, i te mea ka heke te kaha katoa.
Tātai Pūnga Raupapa
Mō ngā pūnga iahiko e honoa ana i roto i te raupapa, ka taea te tatau i te kaha katoa (\( C_{\text{total}} \)) mā te whakamahi i te tātai e whai ake nei:
\[ \frac{1}{C_{\text{total}}} = \frac{1}{C_1} + \frac{1}{C_2} + \frac{1}{C_3} + \ldots + \frac{1}{C_n} \]
kāore i te mana:
– Ko te capacitance katoa o te ara iahiko raupapa \( C_{\text{total}} \),
– Ko te capacitance o ia capacitor takitahi ko \( C_1, C_2, C_3, \ldots, C_n \).
E whakaatu ana tēnei tātai ko te kaha katoa o ngā pūnga raupapa he iti iho i te kaha iti rawa o ngā pūnga takitahi o te ara iahiko.
Tauira Tātaitanga Pūnga Raupapa
Hei mārama ki te whakamahinga o tēnei tātai, me titiro tātou ki tētahi tauira tātaitanga māmā.
Me kī kei a tātou ētahi pūnga iahiko e toru me ngā pūnga iahiko e whai ake nei:
– \( C_1 = 4 \, \kuputuhi{μF} \)
– \( C_2 = 6 \, \kuputuhi{μF} \)
– \( C_3 = 12 \, \kuputuhi{μF} \)
E hiahia ana mātou ki te tatau i te kaha katoa o tēnei ara iahiko raupapa. Mā te whakamahi i te tātai kaha raupapa, ka taea e mātou te tatau penei:
\[ \frac{1}{C_{\text{total}}} = \frac{1}{C_1} + \frac{1}{C_2} + \frac{1}{C_3} \]
\[ \frac{1}{C_{\text{total}}} = \frac{1}{4} + \frac{1}{6} + \frac{1}{12} \]
Tahurihia ngā uara katoa ki te iti rawa o te noa:
\[ \frac{1}{C_{\text{total}}} = \frac{3}{12} + \frac{2}{12} + \frac{1}{12} \]
\[ \frac{1}{C_{\text{total}}} = \frac{6}{12} \]
\[ \frac{1}{C_{\text{total}}} = \frac{1}{2} \]
Mā te huri i tēnei whārite, ka whiwhi tātou:
\[ C_{\kuputuhi{katoa}} = 2 \, \kuputuhi{μF} \]
