Malunga nale Calculator
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 ebuza rhoqo
What is the time constant of an RC circuit?
Ixesha elihlala lihlala τ = R × C lixesha lokuhlawulisa ukuya malunga ne-63% yonikezelo lwe-voltage. Emva kwe-5τ i-condensator ithathwa njenge-charged ngokupheleleyo (>99%).
Ingaba i-condensator igcina amandla amaninzi?
Umandla yi-E = ½ × C × V². I-1000 µF capacitor kwi-5 V igcina i-½ × 0.001 × 25 = 0.0125 joules.
Yintoni utshintsho phakathi kokutshaja nokukhupha?
Ukuhlawula kukhupha ukuya kunikezelo njenge V (1 − e^ (−t/τ)); ukulahla kukhupha ukusuka kukuqala kwe-voltage njenge V·e^ (−t/τ). Zonke zifike ~99% yetshintsho emva kwexesha eliqhubekayo lexesha eli-5.
I-condensator igcina kuphi i-charge?
Ukutshaja kuQ = C × V kwi-coulombs. I-1,000 µF i-condensator kwi-5 V igcina i-0.001 × 5 = 0.005 C. Ukutshaja okukhulu okanye uxinzelelo oluphezulu obomi bokuba gcina ukutshaja okuninzi, kuthelekiswa ngokuthe ngqo.
Ithatha ixesha elingakanani de i-condensator ihlawulwe ngokupheleleyo?
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.
Iphi iphesenti efikelelwe emva kwexesha ngalinye elihlala lihlala?
Ukutyumza kufike malunga ne-63% emva kwe-1τ, 86% emva kwe-2τ, 95% emva kwe-3τ, 98% emva kwe-4τ kunye ne-99% emva kwe-5τ. Ukutyumza kulandele umfanekiso we- mirror: 37%, 14%, 5%, 2% kunye ne- 1% ehlala kwizinto ezifanayo.
Kutheni ukongeza umgca omelanayo?
Umgcini-mandla umisela ukhawuleziso lokufakela. Ngaphandle kwayo i-spike yamandla e-switch-on imiselwe kuphela ngumgcini-mandla ohambayo kwaye inokuba mkhulu; umgcini-mandla usenza ixesha elilindelekileyo, eli lixesha elifanelekileyo le-RC, izihluzi kunye ne-debounce circuits zixhomekeke kuyo.
