On ib multimeter , tsis kawg txhais tau hais tias qhib Circuit Court. Nyob rau hauv ib tug analogue multimeter , tsis kawg tshwm sim raws li ib tug unwavering koob uas yuav tsis txav mus deb ntawm sab laug ntawm cov zaub. On ib digital multimeter , tsis kawg nyeem “0. On ib multimeter , "zero" txhais tau hais tias lub kaw lus kaw tau raug kuaj pom.
Tsis tas li ntawd, dab tsi yog infinity ntawm ohmmeter?
Kaw-Thaum lub sij hawm kaw yog siv nyob rau hauv kev sib raug zoo rau ib tug hluav taws xob Circuit Court nws txhais tau hais tias tam sim no yuav ntws los yog nws muaj continuation. Infinity ohms - Qhov no yog dab tsi ohmmeter nyeem thaum muab tso rau ntawm qhov qhib Circuit Court. Nyob rau hauv ib qho analog meter infinity ua ohms yog thaum rab koob tsis txav txhua qhov thiab ntawm lub ntsuas ntsuas digital infinity ua ohms yog 1.
Ib yam 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.
Nyob rau hauv no txoj kev, dab tsi yog infinite kuj ntawm ib tug digital multimeter?
Thaum koj pom cov infinite kuj ntawm ib tug digital multimeter , nws txhais tau hais tias tsis muaj hluav taws xob tam sim no ntws los ntawm cov khoom koj ntsuas. Yog li ntawd, unlimited tsis kam txhais tau tias cov multimeter tau ntsuas ntau heev tsis kam tias tsis muaj ntws tawm.
Muaj pes tsawg ohms yog qhib Circuit Court?
rau ib qhib Circuit Court , hluav taws xob tsis kam yog infinity vim tsis muaj tam sim no hla lub Circuit Court . ib txwm, R = V / I, qhov twg I = 0A uas ua rau qhov tsis kam ua ntau siab dua uas yog sib npaug rau infinity. luv luv Circuit Court , qhov tsis kam sib npaug rau xoom ohms ua.

Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog qhov txawv ntawm qhov kev txwv tsis kawg thiab kev txwv ntawm infinity?
Daim ntawv ceeb toom yuav ua li cas thaum peb tab tom cuam tshuam nrog qhov kev txwv tsis kawg, nws yog qhov ntsug asymptote. Kev txwv ntawm infinity yog asymptotes ib yam nkaus, txawm li cas los xij, cov no yog kab rov tav asymptotes peb tab tom cuam tshuam nrog lub sijhawm no. Cov kev txwv ntawm infinity muaj teeb meem qhov twg "txwv li x mus txog infinity lossis tsis zoo infinity" yog nyob rau hauv cov cim
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
