Capacitor Discharge Time Constant: The capacitor discharge time constant governs how quickly the capacitor loses its stored charge. Similarly, after one capacitor time constant (τ), the capacitor will have discharged to about 37% of its initial voltage.
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.
At 1 time constant ( 1T ) Vc = 0.37Vc. Therefore, Vc = 0.37 x 10V = 3.7V c) How long will it take for the capacitor to “fully discharge” itself, (equal to 5 time constants) 1 time constant ( 1T ) = 2.2 seconds.
Full charge or discharge after 5 time constants: After 5 time constants, a capacitor is considered nearly fully charged or discharged, reaching over 99% of its total voltage. This means that the capacitor’s behavior stabilizes after 5 τ, and very little change occurs beyond this point.
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
Thus the time constant of the circuit is given as the time taken for the capacitor to discharge down to within 63% of its fully charged value.
