A millihenry ( mH ) yog ib feem kaum ntawm SI muab tau los ntawm inductance henry. Henry txhais tau tias yog inductance ntawm ib lub voj voog, nyob rau hauv qhov kev hloov ntawm tam sim no nrog tus nqi ntawm ib ampere ib ob tsim electromotive quab yuam ntawm ib volt.
Cia li saib qhov no, koj yuav suav Millihenry li cas?
xam inductance siv lej qauv . Pib los ntawm kev sib npaug ntawm qhov tsis kam ntawm qhov resistor los ntawm lub hauv paus square ntawm 3. Piv txwv li, 100 ohms x 1.73 = 173. Tom ntej no, muab 2, pi, thiab zaus. Piv txwv li, yog tias qhov tsis kam yog 20 kHz: 2 * 3.14 * 20 = 125.6.
Qhov thib ob, SI unit ntawm inductance yog dab tsi? Lub henry (cim: H) yog tus SI muab tau chav tsev ntawm hluav taws xob inductance . Cov chav tsev muaj npe tom qab Joseph Henry (1797–1878), tus kws tshawb fawb Asmeskas uas tshawb pom electromagnetic induction nws tus kheej ntawm thiab tib lub sijhawm li Michael Faraday (1791–1867) hauv tebchaws Askiv.
Cov neeg tseem nug, koj yuav hloov Henry rau ohms li cas?
Chav tsev ntawm inductance yog 1H - henry . Yog li, kom tau Ohms faib los ntawm ib tug thib ob. Qhov ntawd tsuas yog tom qab koj faib qhov siv hluav taws xob los ntawm qhov ntsuas inductor tam sim no rau lub sijhawm ntawm ib thib ob.
Dab tsi yog inductance formula?
Yog li, magnetic inductance qauv txhais raws li qhov kev faib ua feem ntawm cov sib nqus flux nyob rau hauv lub caij ntxiv rau cov hluav taws xob tam sim no uas circulates los ntawm lub caij. Yog li ntawd, lub kev sib npaug yuav yog: L = ΦN/I. Ntawm no: L yog hais txog tus inductance.

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?

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
