Yuav ua li cas xam voltage poob nyob rau hauv ib tug tooj liab hlau

  1. Volts = Length x Tam sim no x 0.017. Thaj chaw.
  2. 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.
  3. Sau ntawv.
  4. Piv txwv.
  5. 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:

  1. 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.
  2. Faib 100.
  3. 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.
