Discharging a Capacitor Definition: Discharging a capacitor is defined as releasing the stored electrical charge within the capacitor. Circuit Setup: A charged capacitor is connected in series with a resistor, and the circuit is short-circuited by a switch to start discharging.
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.
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 same ideas also apply to charging the capacitor. During charging electrons flow from the negative terminal of the power supply to one plate of the capacitor and from the other plate to the positive terminal of the power supply.
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
Discharging a capacitor means releasing the stored electrical charge. Let’s look at an example of how a capacitor discharges. We connect a charged capacitor with a capacitance of C farads in series with a resistor of resistance R ohms. We then short-circuit this series combination by closing the switch.
