Ke inductive reactance i ka AC huakai kaapuni

Ia'ku ma ka pou kaapuni mea a mau ano -ʻeleu, a kū'ē. ʻeleu poe resistors, incandescent, paio hahana maoli nō coils, a no laila, ma luna o, Ma nā'ōlelo, a pau nā kumu i loko o i kaʻikena kahe ua pololei hanaʻia pono ka hana paha, i loko o ka hana hihia, e paka i ka makemake paio hahana maoli nō alakaʻi mele. I huli ai oe, o ka mokulele hēkī - he mamalu manawa. Ua pili ia i ka capacitive a me ka inductive reactance. Ka huakai kaapuni a hehee wale me he reactance, i ka hooholo ia o ka uila papa ana likeʻole waena ikehu huli ana. A mea pihana (capacitance) accumulates ka malama, a laila, e hoʻouna aku ia i ka loop. Kekahi kumu hoohalike - ka inductive reactance o ka'ōwili hao, ai ka hapa o ka pou ikehu ua hoohuliia i kaʻume mākenēki kahua.

I ka mea, "maemae" a hana reactances ole. Mau i ke ku pono ana i ke keʻena mea i loaʻa. No ka laʻana, ka wā helu ana i nā kaula no ka lōʻihi-mamao mana laina, lawe i no ole wale i ka ia'ku, aka, i capacitive. A me ka noonoo pono i ka inductive reactance, ka mea pono e hoʻomanaʻo i nā na conductors, a me ka mana lako e hana i kekahi loli ma na helu.

Ma ka hoomaopopo ana i ka huina ia'ku o ka huakai kaapuni hapa, ia mea pono e pa i ka hana a me ka kū'ē eiiiiiaiou. A, e kiʻi i ka pololei huina o ka mau makemakika hana ole, no laila, hoʻohana geometric (maʻi lele) ala, e kūkulu. Kükulu i ka triangle pono kona cathetus mau mea hana a me ka inductive impedance, a me ka hypotenuse - piha. Ka lōʻihi o nā Hoʻohana e like me kaʻikena nā loina.

E hoomanao i inductive reactance i ka AC huakai kaapuni. Ho i kekahi mea kaapuni iloko olaila o ka mana kahi (emf, E), he mea pale mū holapū (resistive ke keʻena, R) a me ka'ōwili hao (inductance, L). Mai ka inductive reactance mea ku pono i ka pakiko-ʻonou EMF (E B) i loko o nā 'ana e haʻalele o ka'ōwili hao, ka mea, ua maopopo i ka mea maoli me ka huakai kaapuni inductance a me ka mea ulu waiwai o ka mea pono e kahe ana ma ka huakai kaapuni.

Ohm ka kānāwai no keia huakai kaapuni a nana e like:

E + E B = Owau no ia R.

Ma hope o hoomaopopo ana i ka manawa derivative o ka papa (I HA) e hoʻomaulia i ka pakiko-hoʻokomo:

E Si = -L * I AVE.

"-" hoailona ma ka helu kaulike Hōʻike i ke kanawai o E iuliabuik olelo ku e hoʻololi i kaʻikena cia. Lenz rula hākālia nō ia ina he mea kekahi loli ana i kaʻikena pakiko-ʻonou EMF. No ia mau loli i ka wahi i puhi ai AC e maoli (a me ka mea a eia i), ka E Bʻano he lula 'ia'ku paha ia i ka oiaio e kū'ē'ē mai. Ina o ka mana kumu o ke ala pono , i kēia pilina mea e māʻona, a i ka wa i hoao e hoʻohui i ka'ōwili hao (inductance) i loko o ia ke kaapuni makemake pōkole-huakai kaapuni ana Classic

E lanakila i ka E B mana lako pono paha kekahi ikehu likeʻole i loko o nā kūʻiʻoa'ōwili hao e ka mea, ua lawa, ma ka liʻiliʻi loa ma ka E iuliabuik ia'ku uku. It penei:

U = -e popoki iuliabuik.

Ma nā hua'ōlelo, ke anakahi uila ma ke inductor ka heluna hapauuku like i ka electromotive ikaika o ka hoʻoponopono-hoʻokomo.

No ka mea, me ka hoʻoulu kala pono i loko o ka huakai kaapuni maoli kaʻume mākenēki kahua ma ka huli paha ke eddy kahua e kauoha ana ka ulu ana i loko o countercurrent inductance, i kekahi ke hai aku i ka mea, he pae naeaeaa ma waena o anakahi uila a me kaʻikena. Keia wahi aku kekahi hiʻona: no ka mea, i ka pakiko-hoʻokomo EMF ua ālai 'kekahi loli ma ka papa, i ka wa a ka mea maoli he (ka mua hapaha au o ka sinusoid i loko o) loan ke kahua ua ua loaʻa, akā, no ka haule ana (lua o ka manawa) ma luna o ka mea ku ole - ka poloʻai pule he mea codirectional i ka waihona ipu. Ia mea, ina o ka postulate ke ola ana o ka maikaʻi mana kumu me na ia'ku a me inductance me kaʻeleu ke keʻena, ai ka kamakawiwo ole ikehu "kumu -'ōwili hao" hiki ana loa.
