AI Customer ServiceIn both charging and discharging processes of a capacitor through a resistance, the current always decreases from its maximum value to zero. What is discharging of a capacitor? The discharging of a capacitor is the process through which stored charge within the capacitor is released.
As soon as the capacitor is short-circuited, it starts discharging. Let us assume, the voltage of the capacitor at fully charged condition is V volt. As soon as the capacitor is short-circuited, the discharging current of the circuit would be – V / R ampere.
Consider a circuit having a capacitance C and a resistance R which are joined in series with a battery of emf ε through a Morse key K, as shown in the figure. When the key is pressed, the capacitor begins to store charge. If at any time during charging, I is the current through the circuit and Q is the charge on the capacitor, then
The discharging of a capacitor is the process through which stored charge within the capacitor is released. What is the role of a dielectric in a capacitor?
When a voltage is placed across the capacitor the potential cannot rise to the applied value instantaneously. As the charge on the terminals builds up to its final value it tends to repel the addition of further charge. (b) the resistance of the circuit through which it is being charged or is discharging.
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.
