How do you calculate the time to discharge a capacitor?
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.
What happens when the capacitor is discharged?
The capacitor is discharged approx. 99.33% after a period of 5 τ. This means that at specified times, well over 5 τ the charging voltage is close to zero. If you move the mouse over the graphic, the charging voltages of different times are displayed.
How does initial voltage affect a capacitor?
The initial voltage (Vi) directly influences the amount of energy stored in the capacitor at the beginning of the discharge process. A higher initial voltage means more stored energy, resulting in a longer discharge time under the same resistance (R) and capacitance (C) conditions.
