Pehea e hoʻokaʻawale ai i ka uea ʻino a me ka maikaʻi (2 ala alakaʻi)

Ma ke ola maoli, ʻaʻole hōʻailona ʻia nā uea a pau e like me ka ʻulaʻula (nā uea maikaʻi) a i ʻole ka ʻeleʻele (nā uea maikaʻi ʻole). No laila, pono ʻoe e ʻike i nā ala ʻē aʻe e hoʻoholo ai i ka polarity o nā uea.

Hiki iaʻu ke hoʻohana i ʻelua uea o ke kala like me ka maikaʻi a me ka maikaʻi ʻole? ʻAe hiki nō. Hiki i kekahi mau ʻoihana a i ʻole kanaka ke koho e hoʻohana i nā uwea o ka waihoʻoluʻu like no nā pilina maikaʻi a maikaʻi ʻole. Ma ia kūlana, e paʻakikī ke hoʻokaʻawale i nā uea mai kekahi i kekahi.

Ua hoʻohana au i nā uea he nui o nā waihoʻoluʻu like ʻole a i kekahi manawa ke kala like ʻole no nā uea maikaʻi a me ka ʻole. Hana wau i kēia no ka mea hiki iaʻu ke hoʻokaʻawale iā lākou me ka ʻole o ka haunaele, ma muli o koʻu mau makahiki o ka ʻike me ka uila.

Ma kēia alakaʻi, e hōʻike wau iā ʻoe pehea e ʻike ai i nā uea maikaʻi a maikaʻi ʻole o kēlā me kēia ʻano pili.

ʻO ka mea maʻamau, ua kaha ʻia nā uea maikaʻi i ka ʻulaʻula a ʻeleʻele nā ​​uea maikaʻi ʻole. Eia nō naʻe, hiki ke hoʻohana ʻia nā uea ribbed, nā uea kālā, a i ʻole nā ​​uea ʻulaʻula no nā uea maikaʻi ʻole. I loko o ke kukui uila, maikaʻi ka uea ʻeleʻele, a maikaʻi ʻole ka uea keʻokeʻo. ʻO nā uwea keleawe he mea hoʻohui ma ka leo. E ʻoluʻolu e hoʻomaopopo he mau ʻāpana wela a kū ʻole nā ​​mea hana - he mau ʻaoʻao maikaʻi a maikaʻi ʻole kēia, ʻaʻole nā ​​uea maoli. I kekahi manawa ua kapa ʻia nā uea maikaʻi a maikaʻi ʻole "+" a i ʻole "-" a hiki iā ʻoe ke ʻike maʻalahi iā lākou.

Kaʻina 1: Pehea e ʻike ai i ka uea maikaʻi a maikaʻi ʻole i nā kūlana maʻamau

E aʻo pehea ʻoe e ʻike ai i nā uea e lawe ana i ka volta mai ka honua - Ke kamaʻilio nei wau e pili ana i nā uea maikaʻi ʻole i nā hiʻohiʻona maʻamau. Mai hoopa aku i na uwea olohelohe me ka lima lima ole. E hoʻopaʻa iā ʻoe iho me kahi mea hōʻike hana - he hoʻopunipuni kekahi mau mea hoʻāʻo, no laila e hoʻāʻo ʻoe iā lākou no nā uea e lawe ana i ka uku.

Pākuʻi no nā mea hana hale

ʻAʻohe ʻaoʻao a i ʻole nā ​​ʻaoʻao maikaʻi a maikaʻi ʻole i nā plugs. He mau ʻāpana wela a kū ʻole nā ​​plug ma kahi o nā uwea maikaʻi a maikaʻi ʻole a i ʻole nā ​​ʻaoʻao. 

ʻO nā kaula hoʻonui a me ke keleawe

E ʻimi i nā uwea i hoʻopaʻa ʻia ma ke kaula hoʻolōʻihi - ʻaʻole maʻamau. Inā like nā kala o kāu mau uea, he keleawe maʻamau, ʻo ka uea maikaʻi ʻole ke ʻano ribbed. E ʻimi i ka lōʻihi o ka uea me kou mau lima e ʻike i nā wahi kuapo e lilo i ka uea maikaʻi ʻole.

ʻO ke kikowaena mālamalama

No ka hoʻoholoʻana i keʻano o nā uea i loko o kahi kukui uila, e hoʻomanaʻo e loaʻa iʻekolu mau kaula - maikaʻi, maikaʻiʻole a me ka lepo. He maikaʻi ka uwea ʻeleʻele, ʻaʻole maikaʻi ka uea keʻokeʻo, a ʻo ka uwea ʻōmaʻomaʻo ka lepo. No laila, inā makemake ʻoe e kau i kahi chandelier, e hoʻolohe i kēia ʻōnaehana uila, akā e hoʻomau me ka akahele. Hiki iāʻoe ke hoʻopau i nā hoʻololi a iʻole ke kī nui. (1)

Eia naʻe, hiki ke hoʻohana ʻia nā uea keleawe no ka hoʻopaʻa ʻana.

Uea leo kani a me ka mea hoʻonui

ʻO ka maʻamau, ʻoi aku ka maikaʻi o nā uea keleawe i ka leo a i ʻole nā ​​uea amplifier. ʻO nā uea maikaʻi ʻole he mau kaula kala.

E hōʻoia i kāu puke palapala

Hiki iā ʻoe ke hoʻohana i kāu manual e hoʻoholo i ke ʻano o kāu mau uea. Loaʻa i nā ʻano kaʻa like ʻole ka coding uea, no laila e ʻike pono e kūʻai i ka manual pololei.

Kaʻina 2: E hoʻohana i ka multimeter e ʻike i ka uea maikaʻi a me ka ʻole

E hoʻohana i ka multimeter kikohoʻe no ka nānā ʻana i ka polarity o nā uea, hiki ke pōʻino ʻia nā multimeter analog inā pili hewa ka ʻimi.

E hoʻonoho i ka multimeter i ka mana-voltage - e hoʻohuli i ke pihi kelepona koho e kuhikuhi i ka ʻāpana me ka "V" ma hope. E hoʻohui i ke alakaʻi ʻeleʻele i ke awa i kapa ʻia ʻo COM, a laila hoʻohui i ke alakaʻi ʻulaʻula i ke awa i kaha ʻia ʻo "V". ʻO ka hope, e hoʻohui i nā ʻimi e hoʻoponopono i ka multimeter, pono ke kani (multimeter) inā hana. No ka nānā ʻana i ka polarity o nā uea, e hana i kēia:

1. E hoʻokuʻi i kekahi alakaʻi o ka ʻimi i hoʻokahi uea, a laila ʻo ka ʻaoʻao ʻē aʻe i kekahi ʻaoʻao o ka uea ʻē aʻe. Hiki iā ʻoe ke hoʻohana i nā clip alligator ma nā uea.
2. E nānā i ka heluhelu multimeter. Inā maikaʻi ka waiwai, maikaʻi ka uea i hoʻopili ʻia i ka uea ʻulaʻula o ka mea ʻike. E loaʻa iā ʻoe kahi heluhelu e pili ana i ka 9.2V. Ma kēia hihia, ʻaʻole maikaʻi ka uea i hoʻopili ʻia i ka uea ʻeleʻele.
3. Inā maikaʻi ʻole ka heluhelu ʻana, ua hoʻohuli ʻia kāu mau uea - maikaʻi ka uea ma ka uea ʻulaʻula a maikaʻi ka uea ma ka uea ʻeleʻele, e hoʻololi i ke alakaʻi probe. (2)
4. Inā hoʻomau ka waiwai o ka volta maikaʻi ʻole, a laila ua hewa kāu multimeter. E hoʻololi.

E nānā i kekahi o kā mākou ʻatikala ma lalo nei.

• Pehea e hoʻoholo ai i ka uea kuʻuna me ka multimeter
• He aha ka manaʻo o ka volta maikaʻi ʻole ma kahi multimeter
• Pehea e nānā ai i ka uwea lepo kaʻa me ka multimeter
