As the capacitor discharges (Figure 3 (b)), the amount of charge is initially at a maximum, as is the gradient (or current). The amount of charge then drops, as does the gradient of the graph. This is described by.
*In the case of large current discharge, it needs to consider the IR drop, which is caused during the early discharge stage derived from capacitor''s IR (direct current resistance) and the discharge current. *In the case of small current discharge, it needs to consider the discharge current of the capacitor (self-discharge).

A capacitor discharge is a situation that occurs when the electrical field from the voltage source around the capacitor goes down to zero, leading to an electron flow, which causes the potential difference between the two conductive plates to reach zero. This is possible when the charges of the two conductive plates are the same.
Capacitor Discharge Graph: The capacitor discharge graph shows the exponential decay of voltage and current over time, eventually reaching zero. What is Discharging a Capacitor? Discharging a capacitor means releasing the stored electrical charge. Let’s look at an example of how a capacitor discharges.
The time it takes for the capacitor to fully discharge can be calculated using the: t = RCln (V0/Vt) where R is the resistance of the resistor, C is the capacitance of the capacitor, V0 is the initial voltage across the capacitor (10V in this case), and Vt is the voltage at which we consider the capacitor to be fully discharged (0V in this case).
In DC circuits, there are two states when a capacitor is discharging. The first is the temporary state, which is while the capacitor is discharging. The second is the steady state, which is when the capacitor is fully discharged. How long does it take a capacitor to discharge?
