Discharging a Capacitor A circuit with a charged capacitor has an electric fringe field inside the wire. This field creates an electron current. The electron current will move opposite the direction of the electric field. However, so long as the electron current is running, the capacitor is being discharged.
When the capacitor is connected to a battery current will flow and the charge on the capacitor will increase until the voltage across the capacitor, determined by the relationship C=Q/V, is sufficient to stop current from flowing in the circuit. Figure 1 shows a circuit that can be used to charge and discharge a capacitor.
When the capacitor is fully charged (the parking lot is full of charges), and you connect a load (let's say a resistor), the charges move from one side of the plate to the other through the resistor (a current flows through the resistor and there's a voltage drop across the resistor).
However, as the flowing current charges the capacitor, the voltage on the capacitor increases. This voltage opposes the flow of more charge and the current begins to decrease. The rate at which the capacitor charges slows as the current decreases -- as more and more charge builds up the current becomes smaller and smaller.
When a capacitor discharges through a simple resistor, the current is proportional to the voltage (Ohm's law). That current means a decreasing charge in the capacitor, so a decreasing voltage. Which makes that the current is smaller. One could write this up as a differential equation, but that is calculus.
The other factor which affects the rate of charge is the capacitance of the capacitor. A higher capacitance means that more charge can be stored, it will take longer for all this charge to flow to the capacitor. The time constant is the time it takes for the charge on a capacitor to decrease to (about 37%).

As the capacitor charges, the voltage across the capacitor increases and the current through the circuit gradually decrease. For an uncharged capacitor, the current through the circuit will be maximum at the instant of switching. And the charging currents reaches approximately equal to zero as the potential across the capacitor becomes equal to the Source …
Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open. If the voltage is changing rapidly, the current will be high and the capacitor behaves more like a short. Expressed as a formula: [i = C …
At any given voltage level, a larger capacitor stores more charge than a smaller capacitor, so, given the same discharge current (which, at any given voltage level, is determined by the value of the resistor), it would take longer to discharge a …

I understand that as a capacitor charges, the amount of electrons that are deposited on one plate increases, thereby the overall voltage across the capacitor increases.

But what I don''t understand is why this decrease in current is …

When a capacitor is discharged, the current will be highest at the start. This will gradually decrease until reaching 0, when the current reaches zero, the capacitor is fully discharged as there is no charge stored across it. The rate of decrease of the potential difference and the charge will again be proportional to the value of the current.
the charging current decreases from an initial value of (frac {E}{R}) to zero; the potential difference across the capacitor plates increases from zero to a maximum value of (E), when the ...
The rate at which a capacitor charges or discharges will depend on the resistance of the circuit. Resistance reduces the current which can flow through a circuit so the rate at which the charge flows will be reduced with a higher resistance. This means increasing the resistance will increase the time for the capacitor to charge or discharge. It ...

Discharge Characteristics: Awareness of the discharge characteristics of the capacitors and batteries is crucial. Some capacitors may discharge rapidly, while others are designed for slower discharge. Misalignment can lead to damage to the overall circuit or explode the capacitor, as studied by M. R.

RC Circuits. An (RC) circuit is one containing a resisto r (R) and capacitor (C). The capacitor is an electrical component that stores electric charge. Figure shows a simple (RC) circuit that employs a DC (direct current) voltage source. The capacitor is initially uncharged. As soon as the switch is closed, current flows to and from the initially uncharged capacitor.
