Yog li cov khoom siv tsis muaj zog uas siv lub zog, xws li cov khoom siv lossis lub teeb pom kev zoo, yuav muaj lub zog zoo dissipation, thaum lub cev muaj zog, lub zog xws li lub tshuab hluav taws xob lossis roj teeb, yuav muaj Txoj kev muaj zog tsis zoo.
Lub zog puas tuaj yeem cuam tshuam tsis zoo?
Rau qhov nqi me me ntawm u0, lub zog yog muab rho tawm los ntawm cov resistor kom nws ib puag ncig txias, yog li qhia tias lub zog tsis zoo. Qhov voltage yog ib qho thermodynamic kom muaj nuj nqis sawv cev rau qhov sib npaug ntawm cov thermal equilibrium.
Puas yog lub zog ntawm tus resistor ib txwm zoo?
Vim resistors yog qhov muaj txiaj ntsig zoo, cov resistors ib txwm dissipate lub zog. … Tam sim no ntws los ntawm ib tug resistor ua rau nws kub; nws lub zog yog tawg los ntawm tshav kub.
Tus resistor puas muaj lub zog tsis zoo?
Nws tsis tuaj yeem tau txais qhov tsis zoo tiv thaiv nrog cov khoom siv tsis muaj tseeb Peb tuaj yeem pom qhov ntawd los ntawm thermodynamics. Ib qho zoo (zoo) resistor tso tawm cua sov rau ib puag ncig - voltage zaus tam sim no muab peb lub zog dissipated. … Koj tuaj yeem siv cov khoom nquag - xws li. ua haujlwm amplifiers, uas muaj lub hwj chim qhov chaw.
Yuav ua li cas xam lub zog dissipated?
Yuav kom paub, peb yuav tsum muaj peev xwm xam cov hwj chim uas tus resistor yuav dissipate. Yog hais tias ib tug tam sim no kuv ntws los ntawm ib tug muab khoom nyob rau hauv koj Circuit Court, poob voltage V nyob rau hauv tus txheej txheem, ces lub hwj chim dissipated los ntawm lub Circuit Court keeb yog cov khoom ntawm qhov tam sim no thiab voltage: P=I × V
