Ngā Pūnga Hiko: Ngā Wāhanga Hiko Matua
He wāhanga hiko nui ngā pūnga hiko, ā, he maha ngā whakamahinga i roto i ngā ara iahiko hiko. Ko tā rātou mahi matua he penapena me te tuku i te pūngao hiko. Ka matapakihia e tēnei tuhinga te whakamāramatanga o ngā pūnga hiko, ō rātou momo, ngā mātāpono mahi, ngā āhuatanga, me ngā whakamahinga i roto i te oranga o ia rā.
Te Mārama ki ngā Pūnga
Ko te pūnga hiko, e mōhiotia ana ko te whakapūmau hiko, he wāhanga hiko kore e taea te penapena pūngao i roto i te mara hiko. Ko te pūnga hiko he mea hanga mai i ngā ara iahiko e rua e wehea ana e te ārai hiko. Ina tukuna he ngaohiko i waenganui i ēnei ara iahiko e rua, ka kohia he utu hiko ki runga i ngā pereti ara iahiko, ka hangaia he mara hiko i waenganui i a rāua.
Ko te tātai taketake e whakamahia ana hei tatau i te kaha (C) ko:
\[ C = \frac{Q}{V} \]
Kei hea:
– Ko te capacitance i roto i ngā farad (F) ko \( C \),
– Ko te utu hiko i roto i ngā coulomb (C) ko \( Q \),
– Ko te ngaohiko i roto i ngā volts (V) ko \( V \).
Te Mātāpono Mahi o te Pūnga
Ko te kaupapa mahi a te pūnga hiko e ahu mai ana i te penapena o te pūngao hiko i roto i te mara hiko i hangaia i waenganui i ngā pereti kawe hiko e rua. Ina whakamahia he ngaohiko, ka kohikohi ngā utu pai ki runga i tētahi pereti, ā, ka kohikohi ngā utu kino ki runga i tētahi atu. Ka taea te tuku i tēnei pūngao hiko kua rongoatia ina hiahiatia, ka taea ai e te pūngao te mahi hei putunga pūngao rangitahi.
