Discharge method to measure the capacitance of capacitors
voltage
The capacitor discharge when the voltage drops from the main voltage level which it connected to like it connected between (5v and GND ) if voltage drops to 4.1v then the capacitor discharge some of its stored charge,the drop in voltage may caused by many effects like increase in a load current due to internal resistance of non-ideal source .
