Txij li thaum txhua tus resistor hauv Circuit Court muaj tag nrho cov voltage, tam sim no ntws los tus kheej resistors I1 = VR1 I 1 = V R 1, I2 = VR2 I 2 = V R 2, and I3 = VR3 I 3 = V R 3. Kev txuag ntawm tus nqi implies tias tag nrho tam sim no Kuv tsim los ntawm lub hauv paus yog qhov suav ntawm cov dej ntws: Kuv = I1 + kuv2 + kuv3.
Kuj paub yog, dab tsi yog tam sim no nyob rau hauv txhua tus resistor?
Ib lub voj voog yog ib lub voj voog nyob rau hauv uas resistors yog teem nyob rau hauv ib tug saw, li ntawd tam sim no muaj ib txoj kev xwb. Cov tam sim no yog tib yam los ntawm txhua tus resistor . Nrog 10 V roj teeb, los ntawm V = I R tag nrho tam sim no hauv Circuit Court yog: I = V / R = 10 / 20 = 0.5 A. Tus tam sim no dhau txhua tus resistor yog 0.5a.
Ib yam li ntawd, tus qauv los nrhiav tam sim no yog dab tsi? Ohms Txoj Cai thiab Lub Zog
- Txhawm rau nrhiav qhov Voltage, (V) [V = I x R] V (volts) = I (amps) x R (Ω)
- Txhawm rau nrhiav qhov tam sim no, (I) [I = V ÷ R] I (amps) = V (volts) ÷ R (Ω)
- Txhawm rau nrhiav qhov Resistance, (R) [R = V ÷ I] R (Ω) = V (volts) ÷ I (amps)
- Kom pom lub hwj chim (P) [P = V x I] P (watts) = V (volts) x I (amps)
Ib tug kuj yuav nug, tam sim no ntsuas li cas?
Tam sim no tuaj yeem yog ntsuas siv lub ammeter. Hluav taws xob tam sim no tuaj yeem ncaj qha ntsuas nrog lub galvanometer, tab sis txoj kev no cuam tshuam nrog kev rhuav tshem cov hluav taws xob hluav taws xob, uas qee zaum tsis yooj yim. Tam sim no tuaj yeem yog ntsuas tsis tawg lub Circuit Court los ntawm kev ntes cov magnetic teb txuam nrog rau tam sim no.
Txoj cai voltage divider yog dab tsi?
Cov txoj cai faib voltage ( voltage divider ) yog ib qho yooj yim txoj cai uas tuaj yeem siv rau hauv kev daws teeb meem kom yooj yim rau kev daws teeb meem. Thov lub txoj cai faib voltage kuj tuaj yeem daws cov kab hluav taws xob yooj yim kom huv. Txoj cai Voltage Division : Cov hluav taws xob yog muab faib nruab nrab ntawm ob series resistors nyob rau hauv ncaj qha proportional rau lawv kuj.

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
Dab tsi yog qhov tam sim no hauv 5 ohm resistor?
Tam sim no los ntawm 5-ohm resistor yog 2.4 amperes
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
