Mokhoa oa ho Khetholla terata e mpe le e ntle (Tsela ea Mekhoa e 2)
Tse ka hare
Bophelong, ha se lithapo tsohle tse tšoailoeng / mebala e le khubelu (lithapo tse ntle) kapa tse ntšo (lithapo tse mpe). Ka hona, o hloka ho tseba mekhoa e meng ea ho tseba hore na polarity ea lithapo ke efe.
A na nka sebelisa lithapo tse peli tsa 'mala o tšoanang le tse ntle le tse mpe? E, hoa khoneha. Lifeme tse ling kapa batho ka bomong ba ka khetha ho sebelisa lithapo tsa 'mala o tšoanang bakeng sa likhokahano tse ntle le tse mpe. Boemong bo joalo, ho tla ba thata ho khetholla lithapo ho tloha ho tse ling.
Ke ne ke sebelisa lithapo tse ngata tsa mebala e fapaneng 'me ka linako tse ling esita le' mala o tšoanang bakeng sa lithapo tse ntle le tse mpe. Ke etsa sena hobane ke khona ho ba arola ntle le moferefere, ho latela phihlelo ea ka ea lilemo tsa motlakase.
Tataisong ena, ke tla u bontša mokhoa oa ho khetholla lithapo tse ntle le tse mpe tsa mofuta ofe kapa ofe oa khokahano.
Ka tlwaelo mehala e phosetifi e tshwauwa e le kgubedu le mehala e mebe e ntsho. Leha ho le joalo, lithapo tse nang le likhopo, lithapo tsa silevera, kapa lithapo tse mebala e khubelu le tsona li ka sebelisoa bakeng sa mehala e mebe. Sebakeng sa mabone, terata e ntšo e ntle, 'me terata e tšoeu e mpe. Lithapo tsa koporo ke li-pluses ho sebui. Ka kopo hlokomela hore li-plug tsa lisebelisoa li na le likarolo tse chesang le tse sa jeleng paate - tsena ke mahlakoreng a matle le a fosahetseng, eseng lithapo tsa sebele. Ka linako tse ling lithapo tse ntle le tse mpe li ngotsoe "+" kapa "-" 'me u ka li tseba habonolo.
Mokhoa oa 1: Mokhoa oa ho khetholla terata e ntle le e mpe maemong a tloaelehileng
Ha re ithuteng hore na o ka tseba joang lithapo tse tsamaisang voltage ho tloha fatše - ke bua ka lithapo tse mpe maemong a tloaelehileng. U se ke ua tšoara lithapo tse se nang letho ka matsoho. Itlhomelle ka sehlahlobi se sebetsang - liteko tse ling lia thetsa, kahoo etsa bonnete ba hore u li lekola bakeng sa lithapo tse nang le tefiso.
Li-plug tsa lisebelisoa tsa lapeng
Li-plug tsa lisebelisoa ha li na lithapo tse ntle le tse mpe kapa mahlakoreng. Li-plug li na le likarolo tse chesang le tse sa nke lehlakore ho e-na le lithapo tse ntle le tse mpe kapa mahlakoreng.
Lithapo tsa katoloso le koporo
Sheba lithapo tse nang le likhopo holim'a khoele ea katoloso - hangata li mpe. Haeba lithapo tsa hau li na le mebala e tšoanang, hangata koporo, terata e mpe ke sebopeho sa likhopo. Latela bolelele ba terata ka matsoho a hao ho utloa libaka tse matsutla e tla ba terata e mpe.
Lebone
Ho fumana hore na lithapo li na le sebopeho sa mabone, hopola hore ho tla ba le lithapo tse tharo - tse ntle, tse mpe le tse fatše. Mohala o motšo o positive, terata e tšoeu ke negative, 'me terata e tala ke ea fatše. Kahoo ha u batla ho fanyeha chandelier, ela hloko tsamaiso ena ea lithapo, empa tsoela pele ka hloko. O ka tima li-switches kapa sesebelisoa se seholo. (1)
Leha ho le joalo, lithapo tsa koporo li ka sebelisoa bakeng sa ho thea fatše.
Mehala ea sebuela-hōle le ea amplifier
Hangata lithapo tsa koporo li na le mehala ea sebuela-hōle kapa ea sebuela-hōle. Lithapo tse mpe ke likhoele tsa silevera.
Sheba Buka ea Mong'a hau
U ka sebelisa bukana ea hau ho fumana mofuta oa lithapo tsa hau. Mefuta e fapaneng ea likoloi e na le likhoutu tsa mohala tse fapaneng, kahoo etsa bonnete ba hore u reka bukana e nepahetseng.
Mokhoa oa 2: Sebelisa multimeter ho khetholla terata e ntle le e mpe
Sebelisa multimeter ea digital ho hlahloba polarity ea lithapo, li-multimeter tsa analog li senyeha habonolo haeba probe e hokahane ka phoso.
Beha multimeter ho ea hona joale-voltage - fetola khetho ea ho daela ho supa karolo e nang le "V" haufi le eona. Kopanya letoto le letšo ho boema-kepe bo ngotsoeng COM, ebe o hokela lead lead ho boema-kepe bo tšoailoeng "V". Qetellong, kopanya li-probe ho lokisa multimeter, e lokela ho lla (multimeter) haeba e sebetsa. Ho hlahloba polarity ea lithapo, etsa se latelang:
- Hokela lloto e le 'ngoe ea terata terateng e le 'ngoe ebe e 'ngoe u e kopa ka lehlakoreng le leng la terata e 'ngoe. U ka sebelisa likotoana tsa alligator ho lithapo.
- Sheba lipalo tsa multimeter. Haeba boleng bo le botle, mohala o kopantsoeng le mohala o mofubelu oa sensor o nepahetse. U tla fumana 'malo oa hoo e ka bang 9.2V. Tabeng ena, terata e hokahaneng le terata e ntšo e mpe.
- Haeba 'malo o le mpe, lithapo tsa hau li khutliselitsoe morao - terata e mothapong o mofubelu ha e amohelehe 'me terata e holim'a terata e ntšo e le ntle, fetola terata ea probe. (2)
- Haeba boleng bo fosahetseng bo ntse bo tsoela pele, joale multimeter ea hau e fosahetse. E fetole.
Sheba tse ling tsa lingoliloeng tsa rona tse ka tlase.
- Mokhoa oa ho tseba terata e sa nke lehlakore ka multimeter
- Ho bolela'ng ha voltage e mpe ho multimeter
- Mokhoa oa ho hlahloba terata ea fatše ea koloi ka multimeter
