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.
Zvimwe zvinobvunzwa zvakanyanya
Chii chinonzi nguva yakafanana yeRC circuit?
The time constant τ = R × C is the time to charge to about 63% of the supply voltage. After 5τ the capacitor is regarded as fully charged (>99%).
Ndezvipi zvinhu zvinokonzera kuti simba riite basa rayo?
Nekudaro, simba remagetsi rinogona kunge riine simba rakafanana nesimba remagetsi remagetsi. 1000 µF capacitor pa5 V inochengeta ½ × 0.001 × 25 = 0.0125 joules.
Ndeupi musiyano pakati pekubhadharisa uye kuburitsa?
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.
Ndezvipi zvinhu zvinokonzera kuti magetsi aite basa rake?
Kubhadharisa ndekwe Q = C × V mu coulombs. A 1,000 µF capacitor pa5 V inotora 0.001 × 5 = 0.005 C. Yakakura capacitance kana yakakwira voltage vaviri kuchengeta zvakawanda zvekubhadhara, muchikamu chino.
Ndeipi nguva kusvika capacitor yacho yabhadharwa zvachose?
Muchokwadi, mushure memakore mana nguva yakafanana (5τ = 5RC) iri mukati me1% yezvigadzirwa uye kutariswa sepfupi. Ne 1 kΩ resistor uye 1,000 µF capacitor τ i 1 s, saka zvinokosha kuti inobhadharwa mushure me5 masekondi.
Chii chiyero chinosvika mushure menguva yakafanana?
Charging reaches about 63% after 1τ, 86% after 2τ, 95% after 3τ, 98% after 4τ and 99% after 5τ. Discharging follows the mirror image: 37%, 14%, 5%, 2% and 1% remaining at the same points.
Nei uchiwedzera series resistor pazvinenge zvakakodzera?
Kunyangwe magetsi emagetsi asingabhadharise, simba rakawandisa rinogona kukonzera kusvibiswa kwemagetsi. Resistance inogadzirisa kubhadharisa kwemagetsi. Pasina iyo, kukwira kwemagetsi kunogona kukonzerwa nesimba rakawandisa, uye kunogona kukonzera kusvibiswa kwemagetsi.
