Aangaande hierdie sakrekenaar
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.
Dikwels gevra vrae
Wat is die tyd wat'n RC - kring voortdurend gebruik?
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%).
Hoeveel energie berg'n capacitor?
Energy is E = ½ × C × V². A 1000 µF capacitor at 5 V stores ½ × 0.001 × 25 = 0.0125 joules.
Wat is die verskil tussen die feit dat ons gelaai en ontlaai word?
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.
Hoeveel beheer hou'n kapacitor?
The charge is Q = C × V in coulombs. A 1,000 µF capacitor at 5 V holds 0.001 × 5 = 0.005 C. Larger capacitance or higher voltage both store more charge, in direct proportion.
Hoe lank totdat die gevangenemer ten volle aangekla word?
Dit is feitlik vyf keer dieselfde as vyf keer dat dit binne ongeveer 1% van die voorraad is en as versadig behandel word.'n Paar killa - weerstandsgroep en 1 000 μF capcitor ← is 1 s, en daarom word dit na ongeveer 5 sekondes in wese gelaai.
Watter persentasie word bereik nadat elke keer dieselfde tyd gehad het?
Laaiing bereik ongeveer 63% ná 1 breektium, 86% na 2 bekommeri, 95% na 3 XXIII, 98% na 4 XXIII en 99% na 5 Buchanan. Ontlaaiing volg die beeld van die spieël: 37%, 14%, 5%, 2% en 1% oor op dieselfde punte.
Waarom moet'n reeks weerstandsmiddels bygevoeg word?
Die teenstander stel die versneller. Sonder dit die huidige pen na wissel-on is beperk slegs deur dwaal weerstand en kan wees groot; die teenstander maak die tyd voorspelbaar, wat presies is wat RC tydlers, filters en aflaat kringe vertrou op.
