6 FAQs about [Capacitor itself charged principle picture]
How does a capacitor store charge?
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
What happens when a capacitor is charged and discharged?
In 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.
What is a capacitor in physics?
A Level Physics CIE Revision Notes 19.

What is the purpose of a capacitor in a circuit?
The main purpose of having a capacitor in a circuit is to store electric charge. For intro physics you can almost think of them as a battery. Edited by ROHAN NANDAKUMAR (SPRING 2021) Charging a Capacitor Charging a capacitor isn’t much more difficult than discharging and the same principles still apply.
How does charging a capacitor work?
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.
Why do capacitor charge graphs look the same?
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 following graphs summarise capacitor charge. The potential difference and charge graphs look the same because they are proportional.
