Charging Speed: The speed at which a capacitor charges depends on both voltage and current. Initially, when a voltage is applied to the capacitor, current flows into the capacitor to charge it. The current rate (measured in amperes) determines how quickly charge accumulates on the capacitor plates.
This process will be continued until the potential difference across the capacitor is equal to the potential difference across the battery. Because the current changes throughout charging, the rate of flow of charge will not be linear. At the start, the current will be at its highest but will gradually decrease to zero.
The time it takes for a capacitor to charge to 63% of the voltage that is charging it is equal to one time constant. After 2 time constants, the capacitor charges to 86.3% of the supply voltage. After 3 time constants, the capacitor charges to 94.93% of the supply voltage. After 4 time constants, a capacitor charges to 98.12% of the supply voltage.
When it is connected to a voltage supply charge flows onto the capacitor plates until the potential difference across them is the same as that of the supply. The charge flow and the final charge on each plate is shown in the diagram. When a capacitor is charging, charge flows in all parts of the circuit except between the plates.
When a capacitor charges, electrons flow onto one plate and move off the other plate. This process will be continued until the potential difference across the capacitor is equal to the potential difference across the battery. Because the current changes throughout charging, the rate of flow of charge will not be linear.
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. This time all of the graphs will have the same shape:
Charging and discharging a capacitor When a capacitor is charged by connecting it directly to a power supply, there is very little resistance in the circuit and the capacitor seems to charge instantaneously. This is because the process occurs over a very short time interval. Placing a resistor in the charging circuit slows the process down.

The Capacitor Charging Graph is the a graph that shows how many time constants a voltage must be applied to a capacitor before the capacitor reaches a given percentage of the applied voltage. A capacitor charging graph really shows to what voltage a capacitor will charge to after a given amount of time has elapsed.
This initial high current quickly turns on the transistor. As the capacitor accumulates charge the voltage across its plates increases, thus the base current decreases until it reaches the value if the capacitor is open. With the input at high state and the circuit settled to steady state, the capacitor is charged to the voltage across Rb. The ...
Battery will push current into capacitor so capacitor accumulates charge and voltage rises until it matches the battery voltage when no current flows any more. When disconnected from battery, as there is no current flowing in or out, capacitor keeps voltage. When connected to a load, current flows out from capacitor and as it discharges the voltage will drop. …

When you charge the capacitor the 100k resistor limits the current so the voltage on the capacitor is: $$v = V left( 1 - text{exp} left( - frac{t}{C cdot R}right) right)$$ Where V is size of the input square wave and R is 100k. The discharge current goes mainly through D1 and not through the 100k resistor. So the current is not limited ...
