Raws li ua ntej, yog tias koj lub voj voog txuas ntxiv, qhov screen qhia tus nqi ntawm xoom (lossis ze rau xoom), thiab multimeter beeps. Yog tias qhov screen qhia 1 lossis OL (qhib voj), tsis muaj kev txuas ntxiv-uas yog, tsis muaj txoj hauv kev rau hluav taws xob tam sim no los ntawm ib qho kev sojntsuam mus rau lwm qhov.

Yog li ntawd, nws txhais li cas rau Ohm ib yam dab tsi tawm?

“Ohming tawm lub cev muaj zog yog cov txheej txheem ntawm kev ntsuas hluav taws xob tsis kam ntawm lub cev muaj zog windings thiab sib piv qhov ntawd tsis kam mus rau qhov muaj nuj nqis.

Ib yam li ntawd, koj siv lub ohm meter li cas? Yuav Siv Lub Ohmmeter li cas

  1. Tshem tawm tag nrho thiab / lossis kaw tag nrho lub zog rau lub voj voog uas koj tab tom sim.
  2. Txuas cov kab ntsuas mus rau ohmmeter.
  3. Nrog rau daim ntawv qhia kev pabcuam rau qhov kev ua haujlwm ib txwm muaj rau lub voj voog uas koj tab tom sim.
  4. Teem lub xov tooj mus rau "ohms (Ω)" teeb tsa nrog multimeter.

Ib yam li ntawd, nws tau nug, qhov kev nyeem ntawv ntawm 0 ohms txhais li cas?

Kuj ntsuas nyob rau hauv ohms ua nrog tsis muaj tam sim no ntws los ntawm Circuit Court. Nws qhia tias xoom ohms ua thaum tsis muaj kev tawm tsam ntawm cov ntsiab lus xeem. Qhov no qhia tau hais tias kev txuas ntxiv ntawm cov dej ntws tam sim no hauv lub kaw lus kaw. Nws qhia tias infinity thaum tsis muaj kev sib txuas hauv Circuit Court uas zoo li nyob rau hauv ib qho qhib Circuit Court.

Yuav ua li cas infinite ohms zoo li ntawm ib lub 'meter'?

Thaum ib qho ohmmeter muab tso rau hauv lub kaw lus kaw nws yuav nyeem ohms ua qhov no txhais tau hais tias lub circuit muaj continuity. Infinity ohms -Qhov no yog qhov ohmmeter nyeem thaum muab tso rau ntawm qhov qhib Circuit Court. Nyob rau hauv ib tug analogue ' meter ' infinity ohms yog thaum rab koob tsis txav ntawm txhua qhov thiab ntawm digital ' meter ' infinity ohms yog 1.
