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.
Mafunso ofunsidwa nthawi zambiri
Kodi ndi nthawi yosasinthasintha ya RC mzere?
Nthawi yosasintha τ = R × C ndi nthawi yolipira mpaka pafupifupi 63% ya voltage yopatsa.Pambuyo pa 5τ capacitor amaonedwa kuti ndi yokwanira (> 99%).
Kodi mphamvu yambiri imasunga bwanji capacitor?
Energy is E = ½ × C × V². A 1000 µF capacitor at 5 V stores ½ × 0.001 × 25 = 0.0125 joules.
Kodi pali kusinthana pakati pa kulipira ndi kutulutsa?
Charging rises toward the supply as V(1 − e^(−t/τ)); discharging falls from the starting voltage as V·e^(−t/τ). Both reach ~99% of the change after 5 time constants.
Kodi ndalama zingati ndi capacitor kusonkhana?
Kulipira ndi Q = C × V mu coulombs. A 1,000 µF capacitor pa 5 V ali 0.001 × 5 = 0.005 C. Kukula capacitance kapena kupitilira muyeso onse kusungira zambiri kulipira, m'madera oyenera.
Kodi nthawi yayitali bwanji mpaka capacitor ndi yoyenera?
Practically, after five time constants (5τ = 5RC) it is within about 1% of the supply and treated as full. With a 1 kΩ resistor and 1,000 µF capacitor τ is 1 s, so it is essentially charged after roughly 5 seconds.
Kodi peresenti ndi kukwaniritsidwa pambuyo nthawi iliyonse yosasinthasintha?
Kutulutsa kwamagetsi kumafika 63% pambuyo pa 1τ, 86% pambuyo pa 2τ, 95% pambuyo pa 3τ, 98% pambuyo pa 4τ ndi 99% pambuyo pa 5τ.Kutulutsa kumatsatira chithunzi cha mirror: 37%, 14%, 5%, 2% ndi 1% zimasungidwa pamalo omwewo.
N'chifukwa chiyani kuwonjezera mzere resistor pa zonse?
