Cov ammeter ntsuas tam sim no ntws hauv hluav taws xob Circuit Court. Muaj qhov pib ob hom ammeters siv nyob rau hauv kev lag luam niaj hnub no: lub clamp-on ammeter thiab hauv kab ammeter.

Ntawm no, hom ammeter yog dab tsi?

Hom Ammeter

  • Permanent txav coil ammeter.
  • Tsiv hlau ammeter.
  • Electro-dynamometer ammeter.
  • Rectifier hom ammeter.

Qhov thib ob, DC ammeter yog dab tsi? A DC Ammeter Qhov yog ib qho cuab yeej los ntsuas DC tam sim no. Feem ntau nws muaj cov kauj vab winding ncig los ntawm cov hlau nplaum ruaj khov, qhov winding nws tus kheej yog txuas mus rau taw tes vane uas yog qhov taw qhia koob rau meter tam sim no . Yog li qhov voltage hla qhov shunt tsis kam yog linearly proportional rau qhov ntsuas tam sim no.

Tsis tas li ntawd, dab tsi yog hu ua ammeter?

Ib ammeter (los ntawm Ampere Meter ) yog lub ntsuas ntsuas siv los ntsuas qhov tam sim no hauv Circuit Court. Cov hluav taws xob tam sim no ntsuas hauv amperes (A), yog li lub npe. Cov cuab yeej siv los ntsuas qhov me me tam sim no, nyob rau hauv milliampere lossis microampere ntau yam, raug xaiv los ua milliammeters lossis microammeters.

Dab tsi yog qhov ua haujlwm ntawm ammeter?

Ib ammeter yog ib qho cuab yeej siv rau kev ntsuas hluav taws xob tam sim no hauv units ntawm amperes. Ib ammeter yuav tsum tau txuas nrog nyob rau hauv series nrog txoj kev ntawm qhov tam sim no ntsuas. Kev teeb tsa ammeter nce nyob rau hauv parallel yuav tsim ib tug luv luv Circuit Court thiab yuav tsis ntsuas qhov tam sim no kom raug.
