For instance, it is generally accepted that a capacitor will charge to about 63.2% of the applied voltage in one time constant and will charge to almost full (99.3%) in five time constants. Similarly, it will discharge to 36.8% of its initial voltage in one time constant and will nearly fully discharge (to 0.7%) in five time constants.
9. CHARGING A CAPACITOR At first, it is easy to store charge in the capacitor. As more charge is stored on the plates of the capacitor, it becomes increasingly difficult to place additional charge on the plates. Coulombic repulsion from the charge already on the plates creates an opposing force to limit the addition of more charge on the plates. Voltage across a …

If a capacitor attaches across a voltage source that varies (or momentarily cuts off) over time, a capacitor can help even out the load with a charge that drops to 37 percent in one time constant. The inverse is true for charging; after one time constant, a capacitor is 63 percent charged, while after five time constants, a capacitor is considered fully charged.
