What happens when capacitor gets fully charged?
When a capacitor is fully charged, no current flows in the circuit. This is because the potential difference across the capacitor is equal to the voltage source. (i.e), the charging current drops to zero, such that capacitor voltage = source voltage.
How much charge is on the capacitor when it is fully charged?
Q = CV [ 1-e-t/RC ] After a five-time constant, the capacitor will be fully charged and the charging current will be zero. Considering the charge on the capacitor as a function of time when it is connected in the circuit, the amount of charge at any time instant can be found.
How to discharge a capacitor in the most safely way?

What happens when IC is charging through capacitor?
If Ic is charging current through capacitor then Ic is maximum at the beginning and it slows starts getting smaller until the capacitor is fully charged or the Potential difference built across capacitor is equal to the supply voltage V.
When does a discharging circuit start to discharge?
As the voltage at t = 0 across the capacitors plates is at its highest value, maximum discharge current therefore flows around the RC circuit. When the switch is first closed, the capacitor starts to discharge as shown.
What does VC mean when discharging a capacitor?
This gives the variation of voltage across the capacitor (Vc) while discharging the capacitor as time varies. Where, Vc = Voltage across the capacitor , V = Original voltage of the capacitor , t = time in seconds and = CR = Time constant.
