no difference is there. if you connect an uncharged one to a battery/voltage source,current flow will be there for a short time which will tend to charge or in more precise manner will develop charge on its plates.if you connect this charged one to a resister or some load,then capacitor will itself act as a voltage source sending current in the circuit at the expense of the charge present on it.this is discharging current.both are same bunt one tends to put up charge while other does the opposite.

What is the relationship between resistance and capacitance in a circuit with a capacitor, and how does the resistance affect the charging and discharging process of the capacitor?

In a circuit with a capacitor, resistance and capacitance are related in how they affect the charging and discharging process of the capacitor. Resistance limits the flow of current in the circuit, which affects how quickly the capacitor charges and discharges. Higher resistance slows down the charging and discharging process, while lower resistance speeds it up. Capacitance, on the other hand, determines how much charge the capacitor can store. Together, resistance and capacitance impact the overall behavior of the circuit with a capacitor.


Why in the experiment of flashing and quenching of capacitor the neon bulb start twinkling?

In the experiment of flashing and quenching of a capacitor, the neon bulb twinkles because the charging and discharging of the capacitor cause the voltage across the capacitor to fluctuate rapidly. These fluctuations can cause the neon bulb to turn on and off, leading to the twinkling effect.


What is the relationship between capacitor resistance and the overall performance of an electronic circuit?

The relationship between capacitor resistance and the overall performance of an electronic circuit is that the resistance of a capacitor affects the charging and discharging times of the capacitor, which can impact the timing and stability of the circuit. Higher resistance can lead to slower charging and discharging, potentially affecting the circuit's functionality and efficiency.


Do the time constant remain the same for discharging and charging capacitors?

No, the time constant is different for discharging and charging capacitors. The time constant for charging a capacitor is given by the product of the resistance and capacitance (τ = RC), while for discharging it is given by the product of the resistance and the remaining capacitance (τ = RC).


Why is the charging time of a capacitor lower than the discharging time?

The charging time of a capacitor is usually lower than the discharging time because during charging, the voltage across the capacitor is increasing from zero to its maximum value, which initially allows a higher current to flow. During discharging, the voltage across the capacitor is decreasing from its maximum value to zero, resulting in a lower current flow. This difference in current flow affects the time it takes for the capacitor to charge and discharge.
