Ku saabsan Kalkaaliyahan
Capacitor charge is the electric charge a capacitor holds in the field between its plates, Q = C × V in coulombs, and the energy stored is E = ½ × C × V² in joules, so doubling the voltage quadruples the stored energy. When you charge a capacitor through a series resistor, the voltage does not jump instantly — it rises along the curve V(t) = V × (1 − e^(−t/τ)); discharging, it falls along V(t) = V × e^(−t/τ). Both are governed by the time constant τ = R × C, the natural timescale of the RC circuit.
After one time constant the capacitor reaches about 63% of the supply voltage when charging (or falls to 37% when discharging); after 5τ it is within 1% of its final value and is treated as fully charged or discharged. For example, a 1,000 µF capacitor charged through a 1 kΩ resistor has τ = 1,000 × 10⁻⁶ × 1,000 = 1 second, so it is 63% charged after 1 s and essentially full after 5 s. At 5 V that same capacitor stores Q = 0.001 × 5 = 0.005 C and E = ½ × 0.001 × 25 = 0.0125 J.
Enter the supply voltage, capacitance and series resistance and the calculator returns the full charge, the stored energy, the time constant, the settling time (5τ), the voltage at a chosen instant, and the whole charge or discharge curve. These numbers are the everyday basis for RC timing circuits, power-supply smoothing, debounce delays, flash-photography energy storage and the turn-on delays in analogue electronics.
Su'aalaha badanaa la isweydiiyo
Waa maxay waqtiga joogtada ah ee RC daboolka?
Waqtiga joogtada ah τ = R × C waa waqtigii si ay u cusboonaysiiyaan ilaa ku saabsan 63% ee voltage. ka dib 5τ capacitor waxaa loo tixgeliyaa sida buuxda oo la cusboonaysiiyay (> 99%).
Sidee badan oo tamarta ah ma capacitor kaydin?
Tamarta waa E = ½ × C × V². A 1000 µF capacitor at 5 V dukaamada ½ × 0.001 × 25 = 0.0125 joules.
Maxay tahay farqiga u dhexeeya lacag bixinta iyo soo dejinta?
Charging kor u kacdo xagga abaalmarinta sida V (1 − e ^ (−t / τ)); soo saarka ka hooseysa ka bilaabma voltage sida V·e ^ (−t / τ). Labaduba gaadho ~ 99% ee isbedelka ka dib 5 waqti joogto ah.
Sidee badan oo lacag ah ma capacitor haysta?
Qiimaha waa Q = C × V in coulombs. A 1,000 µF capacitor at 5 V haystaa 0.001 × 5 = 0.005 C. awood weyn ama voltage sare labadaba kaydinta lacag badan, in qaybta toos ah.
Sidee ayey u dheer tahay ilaa capacitor waa buuxa la cusboonaysiiyay?
Si dhab ah, ka dib markii shan waqti joogto ah (5τ = 5RC) waa ka badan 1% ee la siiyo oo loo daweeyo sida buuxda. La 1 kΩ resistor iyo 1,000 µF capacitor τ waa 1 s, sidaas darteed waa si dhab ah la soo diray ka dib markii in ka badan 5 ilbiriqsi.
Waa maxay boqolkiiba la gaadhay ka dib marka waqti kasta oo joogto ah?
Charging gaadhay 63% ka dib 1τ, 86% ka dib 2τ, 95% ka dib 3τ, 98% ka dib 4τ iyo 99% ka dib 5τ. Decharge raacaa sawirka mirror: 37%, 14%, 5%, 2% iyo 1% ka hadhay meelaha isku mid ah.
Maxaa ku daray series resistor dhammaan?
The resistor aasaasay xawaaraha lacagta. Iyada oo aan la taaban karin ee hadda spike at switch-on waa kaliya oo ku xaddidan yahay by iska caabinta xayawaanka iyo waxay noqon kartaa weyn; resistor ka dhigaysa waqti la saadaalin karo, taas oo ah waxa RC timers, filters iyo devounce circuits ku tiirsan.
