Bu hasapçy hakda
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.
Köp soralýan soraglar
RC gyraň wagtyň durnuklylygy näme?
Zaman durnukly τ = R × C, 63% çemesi ätiýaçlyk voltuny doldurmak üçin wagt. 5τ soň kondensatory doly doldurylan hasaplanýar (>99%).
Kondensator näçe energiýa saklaýar?
Enerji E = ½ × C × V². 1000 µF kapasitor 5 V-da ½ × 0.001 × 25 = 0.0125 joules saklaýar.
Çalyp we boşadip arasy nädir?
Çakmak V(1 − e^(−t/τ)) ýaly üpjünçilige tarap gaçýar; çakmak V·e^(−t/τ) ýaly başlanýan çakmakdan aşak düşýär. Ikisi hem 5 wagt durnukdan soň üýtgeşiň ~99% üne ýetýär.
Kondensator näçe tölegini saklaýar?
Karga Q = C × V coulomblarda. 1,000 µF kapasitor 5 Vda 0.001 × 5 = 0.005 C saklaýar. Büyük kapasitans ýa-da ýokary woltaj ikisi hem, dogry proporsiýada, köp karga saklaýar.
Kondensator doly ýüklenjekçe näçe wagt geçdi?
Praktiki, beş wagt durnuklydan soň (5τ = 5RC) ol 1% çäginde we dolu ýaly kabul edilýär. 1 kΩ rezistor we 1,000 µF kapasitor bilen τ 1 s, şuňa görä ol 5 sekuntdan soň ýüklenýär.
Her bir wagt durnukdan soň näçe göterim ýetilmeli?
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.
Näme üçin bir seriýa rezistor goşmak?
Rezistor ýükleme tizligini belleýär. Oňsyz akymyň öçüşi diňe öçüş bilen çäklenýär we uly bolup biler; rezistor wagty öňe görýän, bu RC wagtçylaryň, filtrleriň we debounce gyralaryň esaslanýan zat.
