Similarly, when a capacitor is being discharged in an RC circuit, the time taken for it to reach a particular voltage level is known as the discharging time. This time can be calculated using the formula: (t_{discharge} = RC \ln\left(\frac{V_{initial}}{V_{final}}\right)) ...
Time Constant, RC circuit, ElectronicsIn this experiment, a capacitor was charged to its full capacitance then discharged through a resistor. By timing how long it took the capacitor to fully discharge through the resistor, we can determine the RC time constant using calculus....

RC TIME CONSTANT The time required to charge a capacitor to 63 percent (actually 63.2 percent) of full charge or to discharge it to 37 percent (actually 36.8 percent) of its initial voltage is known as the TIME CONSTANT (TC) of the circuit. The charge and discharge curves of a capacito...
(DC/2) scale. Since the capacitor has a parallel discharge resistor, you will need to modify the connection to remove this discharge resistor from the circuit. 2. Measure the resistance of the Tripplett VOM set on the appropriate voltage scale using the Fluke DMM. 3. Use the Fluke meter ...
