Yuav ua li cas yog lub serial kev twb kev txuas?

Series kev twb kev txuas - nws yog ib tug compound nyob rau hauv uas lub ntsiab yog kev cob cog rua tsuas yog nyob rau ib kawg. Cov kab yog yus nyob rau hauv hais tias nws excludes tej branching.

Lub series kev twb kev txuas ntawm lub thaum uas tig mus yus nyob rau hauv hais tias nws yog ua nyob rau hauv thaum uas tig mus kev twb kev txuas, uas yuav tsum tau muaj yam tsawg ob lub pob hlav.

Resistors - cov no yog cov ntsiab ntawm cov khoom neeg tsim kuj. Lawv yog siv nyob rau hauv electronics li ib tug ntxiv load los txo cov voltage los yog tam sim no Circuit Court. Yuav ua li cas qhov no yog ua li cas?

Yog hais tias tsim nyog los txo tam sim no, nws yog los ib tug series kev twb kev txuas ntawm resistors. Nyob rau hauv cov ntaub ntawv no, tam sim no kuj muaj txhua yog cov tib yam thiab lub peev xwm sib txawv yog txawv. Nws yuav tsum tau muab sau tseg tias tej zaum txawv - uas yog, qhov ntau ntawm cov voltage nco, nws yog nyob ntawm cov kuj ntawm lub resistor.

Piv txwv li, nyob rau hauv ib tug Circuit Court nrog ib tug voltage ntawm 220 V yog kauj kuj yog 1 ohm. Yog hais tias ib tug ntawm nws ob xaus xa theem, thiab lub thib ob - pes tsawg, nyob rau hauv qhov tseeb muaj yuav ib tug luv luv Circuit Court, thiaj li 1 ohm - nws yog heev me ntsis. Muaj yuav tsum yog ib tug lossis loj tam sim no, lub kauj yuav hlawv, thiab yeej tawm lub network. Yog hais tias lub kauj nyob rau hauv series rau muab tso rau ob resistors ntawm 500 ohms, lub luv luv Circuit Court yog tsis tau, thiab cov kauj yuav ua hauj lwm li nws yuav tsum.

Nyob rau hauv thaum uas tig mus kev twb kev txuas ntawm txhua ceg currents yuav txawv, tab sis cov voltage yuav tau tib yam. Yog li, tam sim no tus nqi ntawm txhua feem nyob rau cov kuj ntawm no feem. Qhov no tswvyim yog siv los ua rau kom cov voltage nco. Piv txwv li, cov kuj ntawm lub kauj yog tsim los rau 50 B. Yuav niam no network rau 220, yuav tsum muaj thaum uas tig mus rau xa uas tsim nyog kuj. Nyob rau nws yuav tsim ib tug voltage nco, thiab cov kauj yuav tsis hlawv.

Yog li, thaum uas tig mus thiab serial kev twb kev txuas yog siv nyob rau hauv tshwj xeeb tus neeg mob thiab ua hauj lwm raws li Ohm txoj kev cai.

Yog hais tias nqa tawm ib series kev twb kev txuas ntawm lub LEDs, nws yog tsim nyog los nco ntsoov tias nyob rau hauv cov ntaub ntawv ntawm tsis ua hauj lwm muaj tsawg kawg yog ib tug ntawm lawv yuav tig tawm rau tag nrho cov saw. Raws li twb tau hais, qhov tam sim no ib tug nyob rau hauv qhov chaw ntawm breakage nqi txaus twb nres thiab lub Circuit Court yog lawm. Thaum kev cob cog rua nyob rau hauv parallel, nws tsis muaj nqi uas LED yog cov, lwm yam yuav txuas ntxiv mus hlawv.

Yog hais tias lub series kuj los ntawm kev siv lub tib lub denominations resistors, tag nrho cov nqi ntawm nws yog sib npaug zos rau cov khoom ntawm ib tug tsis kam los ntawm tag nrho cov ntsiab.

Yog hais tias lub resistor qhov tseem ceeb yog sib txawv, ces tag nrho cov kuj yog sib npaug zos rau cov sum ntawm cov resistances ntawm txhua lub caij.

Thaum kev cob cog rua nyob rau hauv thaum uas tig mus count ua dog dig txawv. Piv txwv li, muaj ib cov saw ntawm peb denominations resistances R1, R2, R3. Yuav kom nrhiav tau tag nrho cov kuj ntawm lub Circuit Court nyob rau hauv thaum uas tig mus kev twb kev txuas, nws yog tsim nyog los mus laij lub sum ntawm cov reciprocals ntawm qhov tseem ceeb ntawm cov denominations, i.e. daim ntau quav tso peb fractions 1 / R1 + 1 / R2 + 1 / R3. Cov zauv yog txo mus rau ib tug ntau denominator - thiab xam tshwm sim. Cov uas ua feem yog inverted thiab yog suav hais tias yog zaum kawg tus nqi.

Nyob rau hauv thiaj li yuav tuaj tos tus kuj rau tej Circuit Court, nws yog tsim nyog los ua suav kom raug. Ib cov kws txawj sim mus khaws resistors los ntawm thwmsim. Txawm li cas los, txawm nyob rau hauv cov ntaub ntawv no, yam tsawg kawg roughly paub uas resistor qhov tseem ceeb tej zaum yuav pom.
