Continuity of Protective Conductors ( R1 + R2 , R1 + Rn)
Qhov no xeem qhia txog tej yam tsis raug hauv kev sib txuas lossis kev sib txuas. Nyob rau hauv ib lub nplhaib Circuit Court, nyob thiab lub ntiaj teb yog cross-connected ntawm txhua kawg ntawm lub nplhaib, thiab lub R1 + R2 Kev ntsuas feem ntau yuav zoo ib yam ntawm txhua qhov chaw ntawm lub nplhaib, tshwj tsis yog muaj qhov txhaum.
Ib yam li ntawd, r1 thiab r2 yog dab tsi?
R1 = tsis kam ntawm theem neeg xyuas pib piv txwv li nyob. R2 = resistance of cpc ie earth. Cheers Paul. Tsuas yog kev kho me me, Zs ntawm Kev Txhim Kho Hluav Taws Xob yog qhov impedance ntawm tag nrho cov system, uas yog los ntawm transformer mus rau qhov hluav taws xob qhov hluav taws xob los yog zaum kawg Circuit Court.
Tsis tas li ntawd, vim li cas peb thiaj ua r1 r2 xeem? Rau txhua qhov hluav taws xob ntawm lub voj voog, qhov kev tawm tsam ntawm ob qho tib si nyob thiab lub ntiaj teb conductors ua ke ( R1 + R2 ) yog ntsuas rov qab mus rau qhov chaw. Qhov no xeem kuj tseem pab txheeb xyuas cov teeb meem polarity - piv txwv li, yog tias cov xaim nyob tau raug hloov pauv nrog cov xaim nruab nrab ntawm qhov chaw hauv ib lub voj voog.
Kuj paub, vim li cas koj faib r1 r2 los ntawm 4?
Vim hais tias ib qho RFC yog qhov tseeb ob lub conductors nyob rau hauv parallel, qhov tsis kam yog halved lwm 1/2. Muab ob qho no 1/2s ua ke thiab koj tau 1/ 4 . Yog li ntawd thaum peb ntsuas r1 qib + r2 qib hauv RFC, peb faib los ntawm 4 kom tau R1 + R2.
r1 txhais li cas hauv lej?
R1 (Pib Kawm lej Kev Txawj Ntse) Kev Xeem Kev Xeem.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
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 Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
