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.
The time it takes for the capacitor to fully discharge can be calculated using the: t = RCln (V0/Vt) where R is the resistance of the resistor, C is the capacitance of the capacitor, V0 is the initial voltage across the capacitor (10V in this case), and Vt is the voltage at which we consider the capacitor to be fully discharged (0V in this case).
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.
A capacitor discharge is a situation that occurs when the electrical field from the voltage source around the capacitor goes down to zero, leading to an electron flow, which causes the potential difference between the two conductive plates to reach zero. This is possible when the charges of the two conductive plates are the same.
