Simple Equation for Capacitor Charging With RC Circuits
Summary, the Time Constant is the time to charge a capacitor through a resistor from the initial charge voltage of zero to be around 63.2% of the applied DC voltage source. Time Constant is also used to calculate the time to discharge the capacitor through the same resistor to be around 36.8% of the initial charge voltage.
