Hauv lwm lo lus, i1 / i2 = V2 / V1. Piv txwv li, yog tias cov tam sim no thiab voltage poob los ntawm lub theem nrab coil yog 3 amps thiab 10 volts, thiab qhov voltage poob los ntawm lub thawj coil yog 5 volts, ces tus tam sim no dhau ntawm thawj coil yog 10/5 * 3 = 6 amps. Yog li cov theem nrab muaj tsawg voltage thiab ntau dua tam sim no.
Kuj yuav paub yog, koj yuav ua li cas nrhiav tau lub ntsiab tam sim no ntawm transformer?
Yog vim li cas koj xav tau qhov loj dua transformer los khiav cov khoom siv, koj tseem faib cov wattage los ntawm qhov voltage mus nrhiav qhov tam sim no . Rau 120-volt thawj , 2000-watt transformer , faib 2000 los ntawm 120 rau cov tam sim no (2000 watts / 120 volts = 16.67 amps). Rau 240-volt, 3000-watt transformer , cov tam sim no yog 12.5 amp.
Dhau li saum toj no, dab tsi yog thawj thiab theem nrab tam sim no? Cov tam sim no hauv theem nrab yog cov tam sim no hauv thawj (xav tias ib zaug tig thawj ) muab faib los ntawm tus naj npawb ntawm lem ntawm lub theem nrab . Nyob rau hauv qhov piv txwv ntawm sab xis, 'Kuv' yog tus tam sim no hauv thawj , 'B' yog magnetic teb, 'N' yog tus naj npawb ntawm lem ntawm theem nrab , thiab 'A' yog AC ammeter.
Ntxiv mus, koj yuav ua li cas nrhiav tau lub hauv paus thiab theem nrab ntawm lub transformer?
- Ua ntej tig ON digital multimeter thiab xaiv hom txuas ntxiv.
- Txuas qhov kev xeem coj mus rau Transformer terminals.
- Nyeem qhov ntsuas tus nqi yog tso tawm.
- tso tawm multimeter tus nqi yog nruab nrab ntawm 300 txog 700, sab no yog thawj.
- tso tawm multimeter tus nqi yog nruab nrab ntawm 2 mus rau 3, sab no yog theem nrab.
Tus qauv tam sim no yog dab tsi?
Hluav taws xob Cov qauv tam sim no . Tus nqi ntawm tus nqi ntws los ntawm ib ntu ntawm qee thaj tsam ntawm cov khoom siv hlau yog hu ua hluav taws xob tam sim no . Nws muaj feem xyuam rau qhov tsis kam ntawm cov khoom siv thiab qhov voltage thov kom txav tau tus nqi. Nws ntsuas hauv amperes (A). Hluav taws xob tam sim no = Voltage / Resistance.

Yuav ua li cas koj pom lub kaum sab xis nruab nrab muab qhov chaw thiab lub vojvoog ntawm ib lub sector?
Kev txiav txim siab Central Angle Los ntawm Sector Area (πr2) × (central angle in degrees ÷ 360 degrees) = sector area. Yog hais tias lub hauv paus lub kaum sab xis ntsuas nyob rau hauv radians, lub mis hloov mus ua: sector cheeb tsam = r2 × (central kaum hauv radians ÷ 2). (θ ÷ 360 degree) × πr2. (52.3 ÷ 100π) × 360. (52.3 ÷ 314) × 360
Dab tsi yog thawj theem nrab thiab theem nrab hydrogen?
Primary = hydrogen ntawm ib cov pa roj carbon txuas nrog tsuas yog ib qho ntawm lwm cov carbon. Secondary = ib hydrogen ntawm acarbon txuas rau tsuas yog OB lwm yam carbons. Tertiary = ahydrogen ntawm cov pa roj carbon txuas nrog peb lwm cov pa roj carbon monoxide
Yuav ua li cas koj pom qhov nruab nrab thiab nruab nrab ntawm daim duab peb sab?
Txhawm rau nrhiav qhov chaw nruab nrab ntawm daim duab peb sab, nws yog qhov yooj yim tshaj plaws los kos tag nrho peb qhov nruab nrab thiab nrhiav lawv qhov kev sib tshuam. Txhawm rau kos qhov nruab nrab ntawm daim duab peb sab, ua ntej nrhiav qhov nruab nrab ntawm ib sab ntawm daim duab peb sab. Kos ib kab ntu uas txuas qhov taw tes no mus rau qhov rov qab vertex
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom loj tshwm sim ntawm koj cov khaub ncaws?
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom ntau tshwm sim ntawm koj cov khaub ncaws? Koj mus ncaj qha rau da dej kev nyab xeeb thiab sawb ntawm tag nrho koj cov khaub ncaws
Koj pom qhov nruab nrab thiab nruab nrab hauv tableau li cas?
Kev sib txuas lus cov ntaub ntawv nrog Tableau los ntawm Ben Jones Qhov nruab nrab (lossis nruab nrab) yog txiav txim siab los ntawm kev suav tag nrho cov txiaj ntsig hauv cov ntaub ntawv teev thiab faib los ntawm tus lej ntawm qhov tseem ceeb. Qhov nruab nrab yog tus nqi nruab nrab hauv cov ntaub ntawv teev nyob rau hauv uas qhov tseem ceeb tau muab tso rau hauv kev txiav txim ntawm qhov loj
