Voltage - kukosha pfungwa magetsi okugadzira

Electricity - the kushandiswa nevakawanda muchimiro simba munhu. Pasina kuwedzerera, tinogona kutaura kuti tsanangudzo Magetsi sezvo maerekitironi akarayira inofamba Zvinozivikanwa kunyange kubva chikoro wefizikisi bhuku. Asi pano pane chii voltage pamusoro kuitika uye kuti anopiwa "zvakarongeka kufamba" anopindura kwete vose. Yeuka kuti Erekitironi, zvokutanga kupomera yemagetsi pacharo kuburikidza muitisi hachivaiti. Ukuwo, chete kufamba mhosva pamwe chuma kunoperekedzwa nokuita anobatsira basa muchimiro simba kutendeuka kubva fomu mumwe. Zviri kuburikidza transformations ava Magetsi mune zvimwe zviitiko glows chiedza girobhu racho filament, uye vamwe - rotates ari rotor injini. Muchiitiko chokutanga tine kuchinja zvemagetsi simba kupinda kuchipisa, uye yechipiri - iri rinobva. Energy inopedzwa ichifamba mhosva nokuda kunobva iyo inotsigira Magetsi mudunhu. Ruchiyerera napakati kondakita, pari transports simba EMF panobva kuti mutengi - the filament windings ari injini, etc.

Kana isu Unotsanangura sezvo mamiriro nhamba mhosva inoyerera kuburikidza nemunhu, zvinganzi kuti basa Kuyerera novimba uwandu kupomerwa izvi panguva. Uye chii chinoratidza kuti Magetsi mudunhu? Funga muenzaniso ano kuerera muenzaniso mvura ndege zvinobva pakuvhurwa pakudzika humburumbira izere kumusoro. Fungidzira kuti muenzaniso wedu humburumbira - nemunhu, uye mvura - icho vakawanda mumate ose maerekitironi. Zvino zviri pachena kuti uchibuda paminiti chikwata nguva uwandu mvura anoenderana parameters maviri - nevezera mvura mbiru uri magetsi nematunhu, anonzi voltage, orifice dhayamita uye - imwe analoginen magetsi nemishonga. Kukwirira mvura mbiru iri muenzaniso rinorondedzera rokumusoro zvinogona simba panobva, mirairo droplet-kufanana karwizi maerekitironi izvo kufamba kubva yokumusoro kunzvimbo dzakaderera rukoko. The zvinogona simba pamusoro pemvura vakawanda, i.e. kukwanisa kuita zvimwe anobatsira basa iri okumusoro siyana zvakasiyana. Nokuda dzingangoitika musiyano pakati mvura anogona ichiyerera ichibva mugomba uye kuti kuchinja zvinogona simba mvura mbiru kupinda kinetic simba mvura jeti. Kana kukwirira mvura mbiru zvichiwedzera, dzingangoitika musiyano, kana voltage, kunowandawo, uye ano, kana kupfuura zvazviri, mukanyiwa inoyerera paminiti chairema nguva mvura iri zvakare kuwedzera. Saka, yaida muenzaniso unoratidza Proportional kuti simba kuitika pamusoro voltage zvakananga.

In pfungwa, simba iri goho zvakanyorwa sezvinotevera: I = d (U) * K, pandinenge - ano, U - voltage uye K - nomumwe cho ane zvemagetsi redunhu kupfuura uno mhinduro - the conductivity. Kazhinji Nzira basa itirana pamusoro conductivity pakati R = 1 / K, uye anonzi "kuramba". Kupikiswa Kazhinji sevanhu yaibatsira redunhu mutoro. In watinotevedzera, ichi "Kusaurayiwa" mugomba nharaunda anoshanda kuti ubvise mvura; makuru ndiwo, mukuru wayo permeability, kana, mumutauro magetsi conductivity, saka mvura iyerere kuramba iri shoma.

The muenzaniso anonyatsoratidza somunhu zvinogona simba kupomerwa-droplet aibuda iri kuva kinetic nesimba parukova runoyerera. The repasi nemishonga (kana mukuru conductivity), kunokonzera zvokuimba basa rinoitwa pasi muviri mvura. Nemamwe mashoko, mhando payloads zvakasiyana - a DC converters, dzakadai filament anomuchinja zvemagetsi simba kupinda kupisa uye chiedza, kuti ataure coils vatendeuki magetsi simba mugomba rinobva, etc.

Tichidzokera magetsi nematunhu, tinogona kugumisa kuti simba kuitika pamusoro kuitika Ini voltage U vari nemagetsi parameters kusarudza kuitika basa A (A = U * I).

Kana ichi kuitika vagara vandifungira chitsama Kutamiswa mutariri, uye voltage ndicho chikonzero icho chinokonzera kuti maerekitironi "zvakarongeka" kuenda kubva yakakura kune imwe kukwanisa duku. Kana voltage vasipo, hapana chitsama vakasununguka maerekitironi vari pfuma haiiti kuti kufamba mhosva. Izvi zvinoreva kuti pasina voltage haiiti kuti kuchinjwa simba.

Kuratidzwa zvakanaka zvakabudiswa ndivo Hydroelectric: vanovaka kushandisa hombe pamwero musiyano (zvinogona) emvura. Pano mukanyiwa kudonha mvura akafanana uno, uye musiyano pakati okumusoro dziva pamwero kuridza basa anogona musiyano.
