Voltage poob : Parallel Circuit

Qhov no txhais tau tias cov hluav taws xob poob hla txhua qhov tsuas yog tag nrho hluav taws xob ntawm Circuit Court muab faib los ntawm tus naj npawb ntawm cov resistors hauv lub Circuit Court , los yog 24 V / 3 = 8 V.

Yog li ntawd, koj yuav ua li cas xam qhov muaj peev xwm poob hauv ib lub voj voog?

Tag nrho cov tsis kam ntawm a series ntawm Circuit Court yog sib npaug rau qhov sib npaug ntawm cov neeg tawm tsam. Qhov hluav taws xob siv rau a series ntawm Circuit Court yog sib npaug rau cov lej ntawm tus kheej voltage poob . Cov hluav taws xob poob hla tus resistor hauv a series ntawm Circuit Court yog ncaj qha proportional rau qhov loj ntawm tus resistor.

Tsis tas li ntawd, ntsuas tam sim no li cas? Tam sim no tuaj yeem yog ntsuas siv lub ammeter. Hluav taws xob tam sim no tuaj yeem ncaj qha ntsuas nrog 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.

Tsis tas li ntawd, koj yuav ua li cas thiaj nrhiav tau qhov sib txawv hauv ib lub voj voog?

Cov Muaj peev xwm sib txawv yog qhov poob hauv qhov hluav taws xob uas tshwm sim thoob plaws ib qho resistor li tam sim no ntws los ntawm nws. Hauv ib Circuit Court , Muaj peev xwm sib txawv los yog Voltage (V) = Tam sim no (I) * Resistance (R), los yog sau luv V = I * R. Hauv qhov no, kuv = 5 amps thiab R = 10 ohms, yog li V = I * R = 5 amps * 10 ohms = 50 volts.

Dab tsi yog meant los ntawm tej zaum poob?

Voltage poob yog txhais raws li tus nqi ntawm hluav taws xob poob uas tshwm sim los ntawm tag nrho los yog ib feem ntawm ib tug Circuit Court vim impedance. Ib qho piv txwv zoo siv los piav qhia hluav taws xob , tam sim no thiab hluav taws xob poob yog vaj hose. Cov xwm txheej no ua rau lub nra hnyav ua haujlwm nrog tsawg dua hluav taws xob thawb qhov tam sim no.
