Kalkuleta na lokacin da’irar RC

Samfuran amsawar resistor-capacitor na farko. Yi lissafin ƙarfin lantarki a lokacin da aka zaɓa ko nemo tsawon lokacin da ake ɗauka don cimma maƙasudi tsakanin ƙarfin farko da na ƙarshe. Saukewa:

Madaidaicin oda na farko lumped RC kewaye kawai. Ana ɗaukan R da C akai-akai, matakin shigarwa nan take kuma babu juriya na tushe, ɗigogi, juriyar juzu'i, abubuwa masu cutarwa, lodi, jikewa ko jinkirin sauyawa. Ba ƙirar kewayawa ko shawarar aminci ba. Saukewa:

τ = R · C. V (t) = V∞ + (V₀ - V∞) e^ (-t/τ). Lokacin tashin 10-90% ko faɗuwar lokaci shine kusan 2.197τ don wannan kyakkyawar amsa. Saukewa:

Don ƙididdige lokacin manufa, maƙasudin dole ne ya kasance tsakanin ƙarfin farko da na ƙarshe. Abubuwan shigarwa da sakamako suna iyakance don kiyaye ƙididdiga iyaka. Saukewa:

Ta yaya kuke lissafta madaidaicin lokacin RC? Saukewa:

Tsawon lokaci shine τ = R × C, tare da juriya a cikin ohms da capacitance a cikin farads. Don amsa mataki, V (t) = V∞ + (V₀ - V∞) e ^ (-t / τ). Bayan akai-akai sau ɗaya, amsar ta ƙare kusan 63.2% na jimlar canjin wutar lantarki. Saukewa:

Tambayoyin da ake yawan yi

Ta yaya kuke lissafta madaidaicin lokacin RC? Saukewa:

Tsawon lokaci shine τ = R × C, tare da juriya a cikin ohms da capacitance a cikin farads. Don amsa mataki, V (t) = V∞ + (V₀ - V∞) e ^ (-t / τ). Bayan akai-akai sau ɗaya, amsar ta ƙare kusan 63.2% na jimlar canjin wutar lantarki. Saukewa:

An ɗora ma'aunin da'ira na? Saukewa:

A'a. Lissafi suna gudana a cikin wannan burauzar, kuma ƙimar da kuka shigar ba a ɗora muku ko adana ta wannan kayan aikin ba. Saukewa:

Menene ma'anar kowane lokaci na RC? Saukewa:

Bayan daya τ, cajin capacitor ya kammala kusan 63.2% na matakin ƙarfin lantarki. Mai cajin capacitor yana da kusan kashi 36.8% na bambancin matakin ƙarfin ƙarfin sa saura.

Yaya tsawon lokacin tashin 10-90%? Saukewa:

Don kyakkyawar amsawar RC ta farko, 10-90% tashi ko lokacin faɗuwa shine ln(9) × R × C, kusan 2.197τ. Hanyoyin da'irori na gaske na iya bambanta saboda rashin ƙarfi na tushe da tasirin parasitic. Saukewa:

Wannan samfurin ya haɗa da da'ira duka?

A'a. Samfurin tsari ne na farko tare da juriya ɗaya da capacitance ɗaya. Ba ya kwaikwayi sanduna da yawa, jurewar sassa, rashin ƙarfi na tushe, lodawa, ɗigogi, canjin hali ko iyakokin aminci.
