| Volt | V | Voltage (V, E) Electromotive quab yuam (E) Muaj peev xwm sib txawv (Δφ) |
| Ohm | Ω | Kuj (R) |
| Watt | W | Lub zog hluav taws xob (P) |
Ntawm no, dab tsi yog lub cim rau tam sim no hauv physics?
Cov cim rau tam sim no yog kuv (italic) los ntawm kev siv ntawm a tam sim no . Hauv daim ntawv sib npaug, tam sim no tuaj yeem sau ua… Lub SI unit ntawm tam sim no yog lub ampere [A]. Lub ampère yog ib qho tseem ceeb hauv chav tsev uas txhais los ntawm cov txiaj ntsig ntawm kev sim electromagnetic.
Ib yam li ntawd, vim li cas lub cim rau tam sim no? Cov pa cim rau tam sim no yog kuv, uas yog los ntawm Fabkis kab lus intensité de courant, lub ntsiab lus tam sim no kev siv zog. Tam sim no kev siv zog feem ntau hu ua yooj yim li tam sim no . Qhov kuv cim tau siv los ntawm André-Marie Ampère, tom qab uas lub tsev hluav taws xob tam sim no yog npe.
Piv txwv li, tsab ntawv cim rau tam sim no yog dab tsi?
Cim . Cov pa cim rau tam sim no yog kuv, uas yog los ntawm Fabkis kab lus intensité du courant, ( tam sim no kev siv zog).
Tam sim no yog dab tsi?
Tam sim no yog ib tug khiav ntawm hluav taws xob cov cab kuj, feem ntau electrons los yog electron-deficient atoms. Physicists xav txog tam sim no ntws los ntawm cov ntsiab lus zoo rau cov ntsiab lus tsis zoo; qhov no yog hu ua pa tam sim no los yog Franklin tam sim no . Cov khoom siv hluav taws xob, cov khoom siv hluav taws xob ntau tshaj plaws, raug them tsis zoo.

Yuav ua li cas hloov DC tam sim no rau AC tam sim no?
Lub hwj chim inverter, los yog inverter, yog apowerelectronic ntaus ntawv los yog circuitry uas hloov directcurrent (DC) mus rau alternating tam sim no (AC).Inputvoltage, tso zis voltage thiab zaus, thiab overallpower tuav nyob ntawm tus tsim ntawm lub specificdeviceor circuitry
Dab tsi yog qhov txawv ntawm qhov tam sim no thiab cov khoom siv tam sim no?
Kev khiav ntawm electrons yog hu ua electron tam sim no. Electrons ntws los ntawm qhov tsis zoo terminal mus rau qhov zoo. Pa tam sim no los yog tam sim no yooj yim, coj zoo li cov neeg nqa khoom muaj txiaj ntsig ua rau tam sim no ntws. Pa tam sim no ntws los ntawm qhov zoo davhlau ya nyob twg mus rau qhov tsis zoo
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom loj tshwm sim ntawm koj cov khaub ncaws?
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom ntau tshwm sim ntawm koj cov khaub ncaws? Koj mus ncaj qha rau da dej kev nyab xeeb thiab sawb ntawm tag nrho koj cov khaub ncaws
Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
