Mai: Electronics 101, e ʻaihue paha i nā mea haʻiʻōlelo e hiki mai ana mai kēia
I ka hopena, mālama nā capacitors i ka uku. Nui nā mea āu e hana ai me nā capacitors.
He maikaʻi nā capacitors i nā kānana uila - e kānana i nā alapine (pinepine) āu e makemake ʻole ai.
He kānana haʻahaʻa - ʻike ʻia nā alapine haʻahaʻa ma ka hopena, ʻoki ʻia nā alapine kiʻekiʻe.
ʻO kahi kānana pass kiʻekiʻe - ʻike ʻia nā alapine kiʻekiʻe ma ka hopena, ʻoki ʻia nā alapine haʻahaʻa.
I hui pū ʻia me kahi inductor, hana lākou i kahi kaapuni resonator hiki ke ʻoki wale i kahi ākea haiki o nā alapine (frequency) a i ʻole e hoʻonui nui i kahi alapine hoʻokahi.
ʻO kahi kānana band-pass e ʻae wale i nā alapine kikoʻī e hele.
Hoʻohana pinepine ʻia nā capacitors e kōkua i ka hoʻopaʻa ʻana i kahi lako mana - ʻoiai lākou e hana i kahi shunt i AC akā waiho wale iā DC, inā makemake ʻoe i kahi lako mana paʻa e hoʻohana paha ʻoe i nā capacitors e kāpae i ka walaʻau, e waiho ana i kahi uila DC paʻa maikaʻi ma ka hopena.
He mea kūpono loa nō hoʻi ka pane transient o kahi kaapuni RC no ke kau ʻana i ke manawa.
Pane pōkole o kahi kaapuni RC
Ma muli o ka nui o ka manawa i hiki ke wānana ʻia e hiki ai i kahi volta kikoʻī, hiki ke hoʻohana ʻia e hoʻonohonoho i ka manawa o ka hoʻololi uila.
Hoʻonohonoho ʻia ka manawa e hoʻā ai a me ka manawa e pio ai e ka capacitor a me ʻelua mau resistors i ke kaapuni manawa i hōʻike ʻia ma luna.
Eia hou, ʻoiai lākou e mālama i ka uku, hiki ke hoʻohana ʻia ma ke ʻano he ʻāpana o kahi ʻōnaehana e hoʻololi iā AC i DC.
Me ka hoʻohana ʻole ʻana i ka capacitor, ma kahi o ka rippled DC, ua like ia me kahi nalu sine me ka ʻaoʻao lalo i hoʻohuli ʻia i luna.
He laʻana liʻiliʻi wale nō kēlā. Hana lākou i nā mea he nui, me ka hoʻokaʻawale ʻana a me ka hoʻohui ʻana (nā hana calculus), hoʻokaʻawale i nā kaapuni biased, hoʻololi i ka pae voltage e hoʻoponopono i ka mana, a mālama i ka hoʻopiʻi no ka hoʻohana manawa pōkole.
A laila aia nā mea āpau āu e makemake ʻole ai i ka capacitance, akā pono e hana me ia no ka mea he mea kino ka capacitance, ʻaʻole kahi mea e kū wale ana ma nā hāmeʻa e kuhikuhi ana iā ia. E like me ke kamaʻilio ʻana me ka hōʻailona, ka hoʻopilikia ʻana me ka impedance input a me output, ka hoʻohui ʻana i ka walaʻau, ka naʻau i nā haʻalulu acoustic, a pēlā aku.
