Chii chinonzi Mutemo weOHM? ➡️ Dzidza zviri ZVINYORE Nemaekisesaizi

Nhanganyaya kuMutemo waOmm:

Mutemo waOmm Iyo ndiyo poindi yekutanga yekunzwisisa izvo zvakakosha zvemagetsi. Kubva pane ino maonero zvakakosha kuongorora chirevo cheOmm Mutemo mune inoshanda dzidziso nzira. Nekuda kweruzivo rwedu mumunda, kuongororwa kwemutemo uyu kunotitendera kuti tiite kuti kurota kwevashandi vepo munzvimbo iyi kuve kwechokwadi: shanda zvishoma uye woita zvimwe, nekuti nedudziro chaiyo tinogona kuona uye kuongorora zvikanganiso zvemagetsi. Pakati penyaya ino isu tichataura nezve kukosha kwayo, mabviro, mashandisiro ezvekushandisa uye zvakavanzika kuti unzwisise zviri nani.

¿Ndiani akawana mutemo waOmm?

Georg simon ohm (Erlangen, Bavaria; Kurume 16, 1789-Munich, Chikunguru 6, 1854) aive chiremba wezvechiGerman uye nyanzvi yemasvomhu akapa mutemo waOmm kune dzidziso yemagetsi. [1]. Ohm inozivikanwa nekudzidza nekududzira hukama pakati pesimba remagetsi emagetsi, simba rayo remagetsi uye kuramba, kuumba muna 1827 mutemo une zita rake unotaura izvozvo Ini = V / R. Chikamu chekudzivirira magetsi, iyo ohm, chakatumidzwa zita rake. [1] (ona mufananidzo 1)

Chii chinotaurwa nemutemo waOmm?

La Mutemo waOmm inosimbisa: Iko kusimba kwazvino kuburikidza nedunhu remagetsi kwakanangana zvakananga nemhepo kana magetsi (inogona kuita mutsauko V) uye inopesana zvakaenzana nemagetsi emagetsi ayo ainopa (ona mufananidzo 2)

Uyu ndeimwe yemibvunzo inonakidza kwazvo inodzidziswa nevadzidzi vemagetsi / zvemagetsi ematanho ekutanga, kwatinokurudzira kuti tinzwisise zvakanaka usati waenderera kana kufambira mberi neimwe nhaurwa. Tiri kuzoiongorora nhanho nhanho: Electric nemishonga: Iko kupokana nekuyerera kwemagetsi emagetsi kuburikidza nekondakita. Magetsi emagetsi: Iko kuyerera kwechaji yemagetsi (maerekitironi) anomhanya kuburikidza nekondakita kana zvinhu. Kuyerera kwazvino ndiko kuwanda kwemari pachikamu chenguva, chikamu chayo chekuyera chiri Ampere (Amp). Magetsi anogona kuita mutsauko: Huwandu hwemuviri hunogadzirisa musiyano mune kugona kwemagetsi pakati pemapoinzi maviri.

Kuongorora Mutemo waOmm kuti unzwisise zvakavanzika zvawo

Paunotanga kudzidza mutemo waOhm, vazhinji vanoshamisika, kuti mutemo wakapusa kudaro ungave sei nezvakavanzika? Chaizvoizvo hapana chakavanzika kana tikachiongorora zvakadzama kumagumo kwazvo. Mune mamwe mazwi, kusatarisa mutemo nemazvo kunogona, semuenzaniso, kutigonesa kubatanidzira dunhu remagetsi (muchiitiko, mudziyo kunyangwe padanho remaindasitiri) apo painogona kungove tambo yakakanganiswa kana chinobatanidza. Tichaongorora nyaya nenyaya:

Nyaya 1 (Vhura dunhu):

kuongororwa kwetunhu yakavhurika yemagetsi — Mufananidzo 10 Vhura magetsi wedunhu (https://citeia.com)

Kana isu tikatarisa dunhu mumufananidzo wechigumi, nemutemo waOmm magetsi E10 = 1V uye kuramba mune ino kesi insulator (mweya) iyo inowanzo kuve isingagumi ∞. Saka tine:

Ini = E1 / R
Ini = 10V / ∞ Ω

Iko iko iko iko iko kunowanzo kuve 0 Amp.

Nyaya 2 (Dunhu rakapfupiswa):

Mune ino kesi (mufananidzo 11) magetsi ari E = 10V, asi kuramba ndiko conductor iyo inonzi ine 0Ω, saka zvingave mune iyi nyaya a dunhu pfupi.

Ini = E1 / R
Ini = 10V / 0 Ω

Iko ikozvino kwedzidziso kunowanzo kuve kusingaperi (∞) Amp. Chii chingakanganisa masisitimu ekudzivirira (fuses), kunyangwe mune yedu software yekufananidza yakakonzera yambiro uye maalarm ekukanganisa. Kunyangwe muchokwadi mabhatiri emazuva ano ane dziviriro sisitimu uye yazvino muganho, tinokurudzira vedu vaverengi kuti vatarise kubatana uye vadzivise maseketi mapfupi (mabhatiri, kana dziviriro yavo ikakundikana, inogona kuputika "Chenjedzo").

Nyaya 3 (kubatanidza kana wiring kutadza)

Kana tikatya mudunhu remagetsi magetsi sosi E1 = 10V uye R1 = 10 Ω isu tinofanirwa kuve nemutemo waOmm;

Kudzidzira 5:

Ini = E1 / R1
Ini = 10V / 10 Ω
