One time constant, τ=RC= (3KΩ) (1000µF)=3 seconds. 5x3=15 seconds. So it takes the capacitor about 15 seconds to charge up to near 9 volts. This article explains how long it takes to charge a capacitor. This can be calculated using the RC time constant and waiting 5 time constants, which brings the capacitor to over 99% of the supply voltage.
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.
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.
After 5 time constants, the capacitor will charged to over 99% of the voltage that is supplying. After 5 time constants, for all extensive purposes, the capacitor will be charged up to very close to the supply voltage. A capacitor never charges fully to the maximum voltage of its supply voltage, but it gets very close.
So, the charge time of a capacitor is primarily determined by the capacitor charge time constant denoted as ? (pronounced tau), which is the product of the resistance (R) in the circuit and the capacitance (C) of the capacitor.
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:
