Malunga nale khadi
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.
Imibuzo ebuzwa kaningi
Yini isikhathi esihlala njalo se-RC circuit?
Isikhathi esihlala τ = R × C isikhathi ukukhokha cishe 63% ye voltage ukuhlinzeka. Ngemuva 5τ i capacitor ithathwa njenge ibhekwa ngokuphelele (> 99%).
Ingabe amandla akhona agcinwa yi-capacitor?
Ugesi ngu E = ½ × C × V². I-1000 µF capacitor e-5 V igcina ½ × 0.001 × 25 = 0.0125 joules.
Yini ushintsho phakathi kokukhokhisa nokulahla?
Ukushaja kukhuphuka ku-supply njenge V(1 − e^(−t/τ)); ukushaja kukhuphuka kusuka ku-voltage yokuqala njenge V·e^(−t/τ). Okubo bonke kufinyelela ku ~99% woshintsho ngemuva kwezikhathi ezingu-5 eziqhubekayo.
Ingabe i-capacitor igcina inani elikhulu le-charge?
Izindleko ziyi-Q = C × V nge-coulombs. I-1,000 µF capacitor e-5 V igcina i-0.001 × 5 = 0.005 C. I-capacitive enkulu noma i-voltage ephezulu zombili zigcina izindleko eziningi, ngokuhambisana.
Ngabe kuthatha isikhathi esingakanani kuze kube yilapho i-capacitor ikhokhiswa ngokuphelele?
Ngokungaqondakali, ngemuva kwezinsuku eziyisithupha eziqhubekayo (5τ = 5RC) ingaphakathi ku-1% yokudlalwa futhi iphathwa njengegcwele. Nge-1 kΩ resistor ne-1,000 µF capacitor τ yi-1 s, ngakho-ke ikhokhwa ngemuva kwamasekhondi angama-5.
Ingabe iphesenti lifinyelelwa ngemuva kosuku ngalunye oluqhubekayo?
Ukushaja kufinyelela ku-63% ngemuva kwe-1τ, 86% ngemuva kwe-2τ, 95% ngemuva kwe-3τ, 98% ngemuva kwe-4τ kanye ne-99% ngemuva kwe-5τ. Ukushaja kulandela isithombe se-mirror: 37%, 14%, 5%, 2% ne-1% ehlala ezindaweni ezifanayo.
Kungani ungeza umkhawulo wesigaba ngaso sonke isikhathi?
I-resistor imisa isivinini sokudlulisa. Ngaphandle kwayo, isivinini esiqhubekayo esishintshayo silinganiselwa kuphela yi-stray resistance futhi singaba namandla amakhulu; i-resistor yenza ukubekezelelana kwesikhathi kulindeleke, okuwukuthi, okuwukuthi, RC timers, filters and debounce circuits depend on.
