Kodi zikutanthauzanji madutsidwe ndi

The madutsidwe amadziwika luso chinthu kuchititsa magetsi, mtengo uwu inversely njila kwa resistivity magetsi.

Pankhani mtengo zenizeni, izo zikutanthauza kupeza chizindikiro kuyeza unit yodziwika ndi chinthu. Tiyeni tiyambe ndi zitsanzo yosavuta wamba amene angakuthandizeni msanga kumvetsa chimene chinali kuchitika.

Specific Timizereto - chophweka chizindikiro zimasonyeza unyinji wa mita kiyubiki imodzi zili pansi zinthu zachilendo. Mu nkhani iyi, chizindikiro ndi muyeso wa kilogalamu, ndi chinthu unit mita kiyubiki.

Zikhalidwe za muyeso mu yachibadwa zinthu opaleshoni athandizira kudziwa, monga ukuwonjezeka kuthamanga, mosamalitsa kulankhula, mita kiyubiki chuma chidzakhala ndi misa woposa pa kuthamanga bwinobwino. Poganizira, tiona kuti semiconductors Mwachitsanzo, mwina appreciably kwambiri kusintha kukana magetsi ndi kusintha kutentha kapena illuminance.

Tsopano kubwerera ku funso la chimene ali madutsidwe. Monga tanena mtengo uwu ndi reciprocal wa resistivity, womwe kutanthauziridwa motere:

The resistivity - kulimbikira nkhani ya kyubu ndi mbali ya 1 mita magetsi inawadutsa pansi chikhalidwe kuti utuluke panopa mosamalitsa perpendicular mmodzi wa nkhope kyubu. Mofananamo, mukhoza kuchitira ndi madutsidwe, koma ndi ofunika anawonjezera kuti amafuna muyeso m'mikhalidwe zachilendo kwa nkhani iyi ndi zofunikanso.

Panopa sayansi ankakhulupirira kuti madutsidwe mwachindunji njila kwa lalikulu la mlandu tinthu, magudumu panopa, kuchuluka kwawo m'nkhaniyo ndi buku ndi inversely njila kulipiritsa chonyamulira kuyenda. Kamvedwe ka kutanthauzira umenewu uli malongosoledwe a chake malamulo Ohm alibe ntchito ku mipweya. Pa mtengo wina wa mu atomu mphamvu kumunda Zimachitika ndondomeko ionization, ndi chigumukire panopa kukacha. Kuti ntchito pamene kuwotcherera kapena pulayimale fulorosenti.

Monga njira zothetsera zinthu zambiri zosangalatsa ngati mulankhula izo mmene izi. The madutsidwe njira zimadalira kwenikweni chiwerengero cha onyamula mlandu, ndiwo ufulu ayoni, moyipa mlandu kapena zabwino. Popeza koyera madzi otchezedwa, ayoni zotero, ndi madutsidwe yeniyeni ya madzi pafupi ziro. Izi zikutanthauza kuti panopa mwa madzi oyera sadzapita. zodabwitsazi ndi njira yochokera kwa kuyeza amenewa kapena chodetsa cha madzi, makamaka pH-chinthu.

Madutsidwe Choncho kwambiri kuti akugwiritsabe ntchito zitsulo zamtengo wapatali mu zamagetsi. Chifukwa mtengo kwambiri mkulu kwa chizindikiro ichi, zitsulo wolemekezeka kukhala zofunika mchitidwe zida zolondola chingwe. Ochepa mukudziwa kuti reflectivity wa zitsulo ndi kwakukulukulu amadalira kukana ake, nchifukwa chake kalirole nthawi zambiri ndi yasiliva.
