Qee lub cev paub txog hluav taws xob zoo li qub
A. Tus nqi them
Tus nqi hluav taws xob siv los qhia tias tus nqi hluav taws xob zoo li cas tau qhia los ntawm Q, thiab nws chav nyob yog Coulomb C.
1 Coulomb=1000000 micro libraries
Thaum ntsuas tus nqi thiab tus nqi sib piv ntawm cov hmoov, thiab kev ua tau zoo ntawm cov khaub ncaws tiv thaiv zoo li qub, tus nqi yuav tsum tau ntsuas.
B. Hluav taws xob hluav taws xob
Txij li nws yog qhov yooj yim los ntsuas qhov muaj peev xwm hluav taws xob hauv ntau lub sijhawm, lwm qhov kev siv hluav taws xob hluav taws xob feem ntau yog hluav taws xob muaj peev xwm, thiab nws chav nyob yog volts, tab sis vim tias qhov hluav taws xob hluav taws xob feem ntau yog siab heev, chav loj-kilovolt (kV) feem ntau siv los ntsuas qhov hluav taws xob zoo li qub ntawm ib yam khoom Feem ntau siv txoj hauv kev rau qhov hluav taws xob yog siv qhov tsis sib cuag electrostatic voltmeter, uas tsis kov lub ntsuas kom ntsuas thaum ntsuas, yog li cov electrostatic cuam tshuam rau cov khoom yuav ntsuas yog me me. Feem ntau siv cov ntsuas yog EST101 qhov tawg-pov thawj electrostatic voltmeter.
2. Cov cuab yeej tseem ceeb thiab cuab yeej siv ntsuas hluav taws xob zoo li cas?
Cov cuab yeej ntsuas ntsuas tus nqi hluav taws xob hluav taws xob muaj lub ntsuas hluav taws xob, thiab lub tshuab hluav taws xob hluav taws xob tuaj yeem siv los ntsuas lub peev xwm hluav taws xob. Muaj ntau yam twj paj nruag rau ntsuas hluav taws xob zoo li qub, xws li ntsuas qhov ntsuas siab, them nqi ntsuas thiab lwm yam.
3. Dab tsi yog qhov ntsuas rau ntsuas cov khoom siv hluav taws xob zoo ntawm cov khoom?
Feem ntau siv tsis rau ntsuas ntau npaum li cas cov khoom raug them yog tus nqi hluav taws xob thiab hluav taws xob hluav taws xob, tab sis thaum ntsuas qhov ua tau zoo ntawm cov yas, roj hmab, antistatic pem teb (nto), ntaub pua plag thiab lwm yam ntaub ntawv, feem ntau tsis kam, tiv taus, ntim tiv taus, tiv taus qhov chaw, them (lossis hluav taws xob) ib nrab ntawm lub neej, hluav taws xob hluav taws xob muaj peev xwm, dielectric tsis tu ncua, thiab lwm yam.
