Capacitor Discharge

In AC circuits, a capacitor''s current and voltage have a 90-degree phase difference ‍ In this figure, V(t) is the voltage depending on time, i(t) is the current depending on time, Vm is the peak value of the voltage of the capacitor, Im is the peak value of the alternative current going through the capacitor, and θ is the phase difference between the voltage and the current of the capacitor.

Capacitance, Charging and Discharging of a Capacitor

Then the capacitor starts charging with the charging current (i) and also this capacitor is fully charged. The charging voltage across the capacitor is equal to the supply voltage when the capacitor is fully charged i.e. VS = VC = 12V. When the capacitor is fully charged means that the capacitor maintains the constant voltage charge even if the supply voltage is
