Yuav ua li cas xam voltage poob nyob rau hauv ib tug tooj liab hlau
- Volts = Length x Tam sim no x 0.017. Thaj chaw.
- Volts = Voltage poob . Length = Total Length of wire hauv meters (nrog rau txhua lub ntiaj teb rov xaim). Tam sim no = Tam sim no ( cov amps ) dhau hlau.
- Sau ntawv.
- Piv txwv.
- 50 x 20 x 0.017 = 17. Faib qhov no los ntawm 4 (hla ntu ntawm cov xaim): 17/4 = 4.25V.
Xav txog qhov no, puas yog amperage poob ntawm qhov deb?
Muab tus lej no los ntawm wattage koj xa dhau txoj kab. Qhov no yields amperage poob lawm ib nyob deb.
Kuj Paub, qhov ntev cable cuam tshuam li cas tam sim no? Ntev ntawm hlau yeej muaj nyhuv ntawm tam sim no thiab voltage.. Kev tiv thaiv yog ncaj qha proportional rau ntev . Raws li cov ntev nce, tsis kam nce, raws li qhov tshwm sim tam sim no txo.
Nyob rau hauv kev hwm rau qhov no, koj yuav ua li cas xam voltage poob tshaj qhov deb?
Yuav kom xam voltage poob:
- Muab cov tam sim no hauv amperes los ntawm qhov ntev ntawm Circuit Court hauv ko taw kom tau ampere-feet. Qhov ntev ntawm Circuit Court yog qhov kev ncua deb ntawm lub hauv paus chiv keeb mus rau qhov kawg ntawm lub voj voog.
- Faib 100.
- Muab ntau los ntawm qhov tsim nyog voltage poob tus nqi hauv cov ntxhuav. Qhov tshwm sim yog voltage poob.
Yuav ua li cas koj xam hlau ntev?
Ib zaug koj muaj xam txhais tau tias txoj kab uas hla, muab nws los ntawm pi (3.14); qhov no yuav muab rau koj ntev ntawm hlau rau coil. Rau xam tus ntev ntawm hlau los ua ib tug compression caij nplooj ntoos hlav, multiply ntev ntawm hlau ib coil los ntawm tag nrho cov coils.

Yuav ua li cas koj xam qhov ncig ntawm lub ntiaj teb ntawm nws latitude?
Circumference ntawm lub voj voog yog sib npaug rau 2 π r qhov twg r yog nws lub vojvoog. Nyob rau hauv lub ntiaj teb no, lub circumference ntawm tus kheej ntawm ib tug muab latitude yog 2πr(cos θ) qhov twg θ yog lub latitude thiab r yog lub vojvoog ntawm lub ntiaj teb ntawm kab zauv
Yuav ua li cas koj xam qhov muaj peev xwm poob hauv ib lub voj voog?
Voltage poob: Parallel Circuit Qhov no txhais tau hais tias qhov hluav taws xob poob thoob plaws txhua qhov tsuas yog tag nrho qhov hluav taws xob ntawm lub voj voog muab faib los ntawm tus lej ntawm cov resistors hauv Circuit Court, lossis 24 V / 3 = 8 V
Yuav ua li cas koj xam qhov hnyav thiab qhov sib npaug ntawm lub dav hlau?
Ntxiv tag nrho cov sijhawm mus nrhiav lub sijhawm tag nrho. Faib tag nrho lub sijhawm los ntawm qhov hnyav tag nrho kom pom qhov nruab nrab ntawm lub ntiajteb txawj nqus. Nrhiav tag nrho qhov hnyav thiab qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm qhov nruab nrab ntawm lub ntiajteb txawj nqus daim ntawv qhia hauv koj lub dav hlau POH los txiav txim seb lub dav hlau puas nyob hauv qhov txwv
Yuav ua li cas koj xam voltage poob feem pua?
Txhawm rau xam qhov hluav taws xob poob: Muab ntau qhov tam sim no hauv amperes los ntawm qhov ntev ntawm lub voj voog hauv ko taw kom tau txais ampere-feet. Qhov ntev ntawm Circuit Court yog qhov kev ncua deb ntawm lub hauv paus chiv keeb mus rau qhov kawg ntawm lub voj voog. Faib los ntawm 100. Muab los ntawm qhov tsim nyog voltage nco tus nqi hauv cov ntxhuav. Qhov tshwm sim yog voltage poob
Yuav ua li cas koj xam lub sij hawm nws yuav siv ib yam khoom los poob?
Ntsuas qhov deb ntawm qhov khoom yuav poob hauv ko taw nrog tus pas ntsuas lossis ntsuas daim kab xev. Faib qhov kev ncua deb los ntawm 16. Piv txwv li, yog tias cov khoom yuav poob 128 ko taw, faib 128 los ntawm 16 kom tau 8. Xam cov square root ntawm cov kauj ruam 2 los nrhiav lub sij hawm nws yuav siv cov khoom poob hauv vib nas this
