Munda simba: mamiriro uye chikuru unhu

The yemagetsi munda, maererano ane utano pfungwa zvokutanga, chinhu asi zvinhu svikiro chinokosha kuitika pasi mhosva muviri uye kukanganisa sangano iri kudyidzana pakati miviri yakadaro neumwe zvazvingava finite uye kunyatsoteerera yakaganhurirwa nzvimbo.

It yagara akaratidza kuti wemagetsi munda anogona kuitika vari mira uye kufamba kuTel. The chikuru chiratidzo kuvapo ichi nyaya mhando yayo simba pamusoro yemagetsi mhosva.

Mumwe mukuru quantitative zvechadenga yemagetsi munda ndiyo pfungwa "munda simba". In kusanganiswa nemashoko, ichi izwi rinoreva nhamba simba kuti anoita pabvunzo mutariri zvakananga kuti uwandu mutariri uyu.

E = F / Q pr.

Chokwadi kuti nokubatira kutongwa kunoreva kuti hapana chikamu pakasikwa munda uyu haangavi kugamuchira, uye mutengo wawo muduku zvokuti haitungamiriri chero kukanganisa pakutanga mashoko. Munda kuchinyanya akayera mu V / m, izvo conventionally kuenzana H / C.

The yakakurumbira Chirungu mutsvakurudzi Michael Faraday kwakamboitwa nzira esayenzi cherudo yemagetsi munda kwakajeka. Maererano naye, ichi mhando inokosha nyaya mufananidzo inofanira anomirirwa muchimiro dzamarudzi mitsetse. Kwapera Ivo akazozivikanwa "yemagetsi munda mutsetse," uye nenhungamiro yavo, pachishandiswa mitemo dzinokosha mumuviri, izvozvo rinobatana kutungamirirwa makakatanwa.

Power mitsetse inodiwa kuratidza vakadaro Qualitative zvechadenga kusungika sezvo arambe achirema kana arambe achirema. The arambe achirema kuti kusimba mitsetse kunobva nhamba muzana chikwata nharaunda. Created nesimba mitsetse muenzaniso yokuziva quantitative okuti zvesango simba dzimwe nzvimbo yayo, uye kudzidza sei kuchinja.

Sezvineiwo zvakakwana Zvivako electric munda dielectric. Sezvo chikazozikamwa, dielectrics - nyaya umo hapana kushanda hapana akasununguka mhosva nezvimedu, saka, sezvo zvakaguma havana vanokwanisa kuitisa magetsi ano. Kwakadaro zvinokuvadza zvinofanira kunzi chikuru zvose magasi, Ceramics, porcelain, kwakadonhera mvura, Mika, etc.

Kuti uone munda simba iri dielectric, inofanira napakati yemagetsi munda. Under kwayo chiito ukama mhosva vari dielectric vanotanga Zvisinei, kuchinja, kusiya muganhu mamorekuru avo, havagoni. Dzidziso kutsvetera zvinoreva kuti chokwadi mhosva kutamira nenzira yemagetsi munda, uye okusafarira mhosva - pamusoro. Somugumisiro manipulations izvi mukati dielectric, mutsva yemagetsi munda, inova pakatarisana achitungamirirwa kunze. Izvi munda dzakawanda yekudyidzana kunoderedza kwokunze, saka makakatanwa wekupedzisira madonhwe.

Munda simba raro chinokosha quantitative unhu riri zvakananga zvinoenderana simba nako ino chaiyo mhando nyaya chiito kwokunze yemagetsi mutariri. Pasinei chokwadi kuti ukoshi ichi haichaonekwi tichibatsirwa simba makakatanwa akarongwa kudhirowa, unogona kuwana imwe pfungwa dzayo arambe achirema uye dzidziso zviri muchadenga.
