Hauv ib potentiometer , tag nrho cov input voltage yog siv nyob rau hauv tag nrho ntev ntawm lub resistor, thiab lub tso zis voltage yog qhov voltage poob ntawm qhov ruaj thiab zawv zawg tiv tauj raws li qhia hauv qab no. A potentiometer muaj ob lub terminals ntawm lub input qhov chaw tsau mus rau qhov kawg ntawm lub resistor.

Ib yam li ib tug yuav nug, dab tsi yog 3 tus pins ntawm potentiometer?

A potentiometer muaj 3 pin . Ob cov davhlau ya nyob twg (xiav thiab ntsuab) txuas nrog lub zog tiv thaiv thiab lub davhlau ya nyob twg thib peb (qhov dub) txuas nrog lub wiper adjustable. Cov potentiometer tuaj yeem ua haujlwm raws li rheostat (tsis paub meej resistor) lossis raws li qhov sib faib hluav taws xob.

Yog li ntawd, dab tsi yog siv potentiometer?

Lub ntsuas ntsuas hu ua a potentiometer yog qhov tseem ceeb ntawm qhov sib faib hluav taws xob siv rau kev ntsuas hluav taws xob muaj peev xwm (voltage); cov tivthaiv yog ib qho kev siv ntawm tib lub hauv paus ntsiab lus, yog li nws lub npe. Potentiometers feem ntau yog siv los tswj cov khoom siv hluav taws xob xws li ntim tswj ntawm cov khoom siv suab.

Dab tsi yog 10k potentiometer?

Tus "K" hauv kev sau ntawv luv luv rau "kilohms." Lub ohm yog SI unit ntawm hluav taws xob tsis kam; ib kilohm yog 1000 ohms. Yog li 100K potentiometer muaj kaum npaug qhov tsis kam ntawm a 10K potentiometer muaj.
