Yog hais tias qhov voltage hloov tam sim ntawd los ntawm ib qho nqi mus rau lwm qhov (piv txwv li tsis tu ncua), tus derivative tsis yog qhov kawgQhov no txhais tau hais tias qhov tam sim no tsis kawg yuav tsum tau hloov qhov voltage tam sim. Txij li qhov tam sim no tsis kawg tsis tuaj yeem paub lub cev, qhov ntawd txhais tau hais tias qhov hluav taws xob tsis tuaj yeem hloov pauv sai sai.
Vim li cas capacitor tsis tso cai hloov pauv tam sim?
Kev piav qhia: Capacitor tsis tso cai tam sim ntawd hloov pauv ntawm qhov hluav taws xob vim cov kev hloov no tshwm sim hauv xoom lub sijhawm uas ua rau tam sim no yog infinity, uas tsis tuaj yeem ua tau. … Piav qhia: Thaum cov capacitors txuas nrog hauv cov koob, tus nqi thoob plaws txhua lub capacitor tseem zoo ib yam li qhov voltage hla txhua qhov sib txawv.
Capacitor voltage hloov tam sim no?
capacitors thiab inductors khaws cov hluav taws xob hluav taws xob-capacitor hauv qhov hluav taws xob, inductors hauv qhov chaw sib nqus. … Qhov no tsis yog lub cev ua tau, yog li lub capacitor qhov voltage hloov tsis tau tam sim noFeem ntau, capacitors tawm tsam cov kev hloov pauv ntawm qhov voltage-lawv nyiam "xav" lawv qhov voltage hloov "maj mam ".
Qhov kev hloov pauv ntawm lub capacitor Tsis tuaj yeem hloov tam sim?
Thaum kawg, peb tuaj yeem pom tias qhov hluav taws xob hlatus capacitor hloov tsis tau tam sim. Rau qhov voltage hloov nyob rau hauv xoom lub sij hawm, ces i(c) yuav tsum infinite. Thaum lub capacitor raug them los ntawm qhov hluav taws xob nyob rau hauv series nrog cov resistor, peb tuaj yeem pom tias qhov hluav taws xob hla lub capacitor terminals tsub nqi txawv.
Vim li cas tam sim no hla ib qho inductor hloov tsis tau tam sim?
Tam sim no hauv ib qho inductor hloov tsis tau tam sim no vim nws txhais tau tias qhov hluav taws xob tsis kawg yuav muaj nyob, uas yuav tsis tshwm sim. Qhov tsis kam hloov pauv no yog vim lub zog khaws cia hauv inductor lub magnetic teb. Tam sim no nyob rau hauv ib tug inductor tsis (yuav tsis) hloov instantaneously.
