Find the time to discharge a 470 µF capacitor from 240 Volt to 60 Volt with 33 kΩ discharge resistor. Using these values in the above two calculators, the answer is 21.5 seconds. Use this calculator to find the required resistance when the discharge time and capacitance is specified
This tool calculates the time it takes to discharge a capacitor (in a Resistor Capacitor network) to a specified voltage level. It’s also called RC discharge time calculator. To calculate the time it takes to discharge a capacitor is to enter: The time constant τ = RC, where R is resistance and C is capacitance.
This residual inductance increases with an increase in the length of electrodes. In addition, the narrower the electrode is, the higher the amount of inductance. To reduce this unwanted inductance and improve the filtering performance of capacitors, it is necessary to modify the architecture of these passive components.
because the applied potential difference is shared by the capacitors, the total charge stored is less than the charge that would be stored by any one of the capacitors connected individually to the voltage supply. The effect of adding capacitors in series is to reduce the capacitance.
The capacitors reach their maximum charge when the flow of charge ceases. The total charge is equal to the sum of the charges on the capacitors. The capacitors can be replaced with one capacitor with a capacitance of Ceq. The equivalent capacitor must have exactly the same external effect on the circuit as the original capacitors.
The discharge time of a capacitor is primarily governed by the RC time constant (often denoted as τ), where R is the resistance through which the capacitor discharges, and C is the capacitance. The time constant represents the time required for the voltage across the capacitor to decrease to about 36.8% (substitute t=RC in the equation e−t/RC .

Capacitors are devices that store electric charge. The farad is a large unit, typically you will see microfarads (mF) and picofarads (pF). The capacitance of a given capacitor is constant. The capacitance is a measure of the capacitor''s ability to store charge .
Capacitors favor change, whereas inductors oppose change. Capacitors impede low frequencies the most, since low frequency allows them time to become charged and stop the current. Capacitors can be used to filter out low frequencies. For example, a capacitor in series with a sound reproduction system rids it of the 60 Hz hum.
