He aha ka hōʻailona no nā microfarads ma kahi multimeter?

Inā he uila ʻoe a hoʻomaka paha me ka uila, pono ʻoe e makaʻala i nā ʻāpana uila like ʻole. ʻO kekahi o kēia mau microfarad.

So He aha ka hōʻailona no nā microfarads ma kahi multimeter?? E pane kākou i kēia nīnau.

Ma hea mākou e hoʻohana ai i nā microfarads?

Hoʻohana ʻia nā microfarads i kahi ʻano o nā lako uila, me nā capacitors, transistors, a me nā kaʻa i hoʻohui ʻia.

Akā ʻo ka pinepine ʻoe e hālāwai me lākou i ke ana ʻana i ka capacitance o kahi capacitor.

He aha ka capacitor?

ʻO ka capacitor kahi mea uila i hoʻohana ʻia e mālama i ka uku uila. Loaʻa iā ia nā papa metala ʻelua i hoʻopili ʻia me kahi mea hana ʻole (i kapa ʻia he dielectric) ma waena.

Ke hele ka mana uila ma ka capacitor, hoʻopiʻi ia i nā pā. A laila hiki ke hoʻohana ʻia kēia ikehu uila i mālama ʻia i nā mea uila.

Hoʻohana ʻia nā Capacitors ma kahi ākea o nā mea uila, me nā kamepiula, kelepona kelepona, a me nā lekiō.

ʻElua ʻano nui o nā capacitors:

Polar Capacitors

ʻO nā capacitor polarized kahi ʻano o nā capacitors electrolytic e hoʻohana ana i kahi electrolyte e hāʻawi i kahi ala no nā electrons. Hoʻohana ʻia kēia ʻano capacitor i nā ʻano noi like ʻole me nā lako mana, kamaʻilio, decoupling, a me kāna kānana.

ʻOi aku ka nui o nā capacitors electrolytic a ʻoi aku ka nui o ka capacitance ma mua o nā ʻano capacitors ʻē aʻe.

capacitor non-polar

ʻO nā capacitor non-polar kekahi ʻano o ka capacitor e mālama i ka ikehu i loko o ke kahua uila. ʻAʻole loaʻa i kēia ʻano capacitor kahi electrode polarizing, no laila ua like ke kahua uila.

Hoʻohana ʻia nā capacitors non-polar i nā ʻano mea like ʻole, e like me nā lekiō, televise, a me nā mea uila ʻē aʻe.

He aha nā capacitor terminals?

Loaʻa i kahi capacitor ʻelua mau hopena: kahi pahu maikaʻi a me kahi pahu maikaʻi ʻole. Hoʻopaʻa pinepine ʻia ka pahu maikaʻi me kahi hōʻailona "+", a ʻo ka pahu maikaʻi ʻole me kahi hōʻailona "-".

Hoʻolālā ʻia nā ʻōkuhi e hoʻopili i ka capacitor i ke kaapuni uila. Hoʻopili ʻia ka pahu maikaʻi i ka lako mana a hoʻopili ʻia ka pahu ʻino i ka lepo.

Pehea e heluhelu ai i ka capacitor?

No ka heluhelu ʻana i kahi capacitor, pono ʻoe e ʻike i ʻelua mau mea: ka uila a me ka capacitance.

ʻO ka Voltage ka nui o ka ʻokoʻa ʻokoʻa uila ma waena o nā hopena maikaʻi a maikaʻi ʻole o kahi capacitor. ʻO ka Capacitance ka hiki i ka capacitor ke mālama i kahi hoʻoili uila.

Ua kākau pinepine ʻia ka capacitor ma ka ʻaoʻao o ka capacitor.

ʻO ka hōʻailona Microfarad ma kahi multimeter

ʻO ka hōʻailona no nā microfarads he "uF", āu e ʻike ai ma ke kelepona o kāu multimeter. Hiki iā ʻoe ke ʻike iā ia i kākau ʻia ma ke ʻano he "uF". No ke ana ʻana i nā microfarads, hoʻonoho i ka multimeter i ke kūlana "uF" a i ʻole "uF".

ʻO ka ʻāpana maʻamau no ka capacitance he farad (F). ʻO ka microfarad ka hapa miliona o ka farad (0.000001 F).

Hoʻohana ʻia kahi microfarad (µF) e ana i ka capacitance o kahi mea uila a i ʻole kaapuni. ʻO ka capacitance o kahi ʻāpana uila a i ʻole kaapuni ka hiki ke mālama i kahi uku uila.

Nā manaʻo kumu e pili ana i ka ʻāpana Farad

ʻO Farad kahi ʻāpana o ke ana no ka capacitance. Ua kapa ʻia ʻo ia ma hope o ka physicist Pelekane ʻo Michael Faraday. ʻIke ʻia ka farad i ka nui o ka uku uila i mālama ʻia ma kahi capacitor.

Ma ka papaʻaina hiki iā ʻoe ke ʻike i nā ʻāpana like ʻole o ka farad, a me kā lākou mau ʻāpana.

ʻO ka nui o ka mana i nā farads

Pehea e ana i ka microfarad?

No ka hoʻāʻo ʻana i ka capacitance o kahi capacitor, pono ʻoe i kahi multimeter hiki ke ana i nā microfarads. ʻAʻole loaʻa kēia hiʻohiʻona ka hapa nui o nā multimeters.

Ma mua o ke ana ʻana, e hōʻoia e hoʻokuʻu i ka capacitor i ʻole e hōʻino i ka multimeter.

E hoʻomaopopo mua i ka hopena maikaʻi a me ka maikaʻi ʻole o ka capacitor. Ma kahi capacitor polarized, e kaha ʻia kekahi o nā hopena "+" (maikaʻi) a ʻo kekahi "-" (negative).

A laila e hoʻohui i ke alakaʻi multimeter i nā hopena capacitor. E hōʻoia i ka pili ʻana o ka ʻeleʻele i ka pahu ʻino a ua hoʻopili ʻia ka ʻulaʻula i ka pahu kūpono.

E hoʻā i kāu multimeter a hoʻonoho iā ia e ana i nā microfarads (uF). E ʻike ʻoe i ka heluhelu ʻana i nā microfarads ma ka hōʻike.

I kēia manawa ua ʻike ʻoe i ke ʻano o ka hōʻailona microfarad a pehea e ana ai iā lākou, hiki iā ʻoe ke hoʻomaka e hoʻohana iā lākou i kāu mau papahana uila.

Nā Manaʻo Palekana Ke hoʻāʻo nei i nā Capacitors

Pono ke ana ana i na capacitors i kekahi mau kaohi.

Me ka noʻonoʻo a me ka noʻonoʻo, hiki iā ʻoe ke ana i nā capacitors me ka ʻole o ka hōʻino ʻana i ka hāmeʻa e ana iā lākou a iā ʻoe iho.

• E hoʻohana i nā mīkina lima mānoanoa e pale i kou mau lima.
• Inā paʻi ʻia ka capacitor i kou kino (e like me ke ana ʻana iā ia ma ke kua o ka mea hoʻonui a i ʻole kahi paʻa ʻē aʻe), e kū ma kahi maloʻo a i hoʻopaʻa ʻia (e like me ka moena wili) e pale i ka haʻalulu uila.
• E hoʻohana i ka voltmeter kikohoʻe pololei i hoʻonohonoho pono ʻia i ka laulā kūpono. Mai hoʻohana i ka voltmeter analog (pane hoʻoneʻe) hiki ke hōʻino ʻia e ke au kiʻekiʻe i ka wā e hoʻāʻo ai i nā capacitors.
• Inā ʻaʻole ʻoe maopopo inā ua polarized ka capacitor (loaʻa nā + a me - terminals), e nānā i kāna ʻikepili. Inā nalo ka ʻikepili, e noʻonoʻo ua polarized.
• Mai hoʻopili pololei i ka capacitor i nā pahu lako mana no ka mea e hōʻino paha kēia i ka capacitor.
• Ke ana ʻana i ka volta DC ma luna o kahi capacitor, e makaʻala e pili ana ka voltmeter ponoʻī i ka heluhelu. No ka loaʻa ʻana o ka heluhelu pololei, e ana mua i ka voluma me ka pōkole o nā uea mika, a laila e unuhi i kēlā voli "biased" mai ka heluhelu ʻana me nā uwea mika i hoʻopili ʻia i ka capacitor.

hopena

I kēia manawa ua ʻike ʻoe i ke ʻano o ka hōʻailona microfarad, hiki iā ʻoe ke ana wale i ka capacitor me kahi multimeter kikohoʻe. Manaʻo mākou ua kōkua kēia alakaʻi iā ʻoe e hoʻomaopopo i ka hana ʻana o nā farad ma ke ʻano he ʻāpana o ke ana.
