A fully charged capacitor discharges to 63% of its voltage after one time period. After 5 time periods, a capacitor discharges up to near 0% of all the voltage that it once had. Therefore, it is safe to say that the time it takes for a capacitor to discharge is 5 time constants. To calculate the time constant of a capacitor, the formula is τ=RC.
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
To calculate the time constant of a capacitor, the formula is τ=RC. This value yields the time (in seconds) that it takes a capacitor to discharge to 63% of the voltage that is charging it up. After 5 time constants, the capacitor will discharge to almost 0% of all its voltage.
After 2 time constants, the capacitor discharges 86.3% of the supply voltage. After 3 time constants, the capacitor discharges 94.93% of the supply voltage. After 4 time constants, a capacitor discharges 98.12% of the supply voltage. After 5 time constants, the capacitor discharges 99.3% of the supply voltage.
For the equation of capacitor discharge, we put in the time constant, and then substitute x for Q, V or I: Where: is charge/pd/current at time t is charge/pd/current at start is capacitance and is the resistance When the time, t, is equal to the time constant the equation for charge becomes:
