The charge and discharge of a capacitor
The charge and discharge of a capacitor. It is important to study what happens while a capacitor is charging and discharging. It is the ability to control and predict the rate at which a capacitor charges and discharges that makes capacitors
Charging and Discharging a Capacitor
When the capacitor begins to charge or discharge, current runs through the circuit. It follows logic that whether or not the capacitor is charging or discharging, when the

As it is continuously charged and discharged by electricity flow, there is no need for separate charging of the ac capacitor. I hope this answers your quest to does a new ac capacitor need
18.4: Capacitors and Dielectrics
In storing charge, capacitors also store potential energy, which is equal to the work (W) required to charge them. For a capacitor with plates holding charges of +q and -q,
resistors
After 5 time periods, a capacitor charges up to over 99% of its supply voltage. Therefore, it is safe to say that the time it takes for a capacitor to charge up to the supply
Capacitance and Charge on a Capacitors Plates
Where A is the area of the plates in square metres, m 2 with the larger the area, the more charge the capacitor can store. d is the distance or separation between the two plates.. The smaller is this distance, the higher is the ability of the
Can you charge a capacitor with very high voltage and no or little
No. You must supply charge, to charge a capacitor. A flow of charge is current. With a small capacitor, it would be a small charge, but a finite current has to flow for a finite

6 FAQs about [No need to charge the capacitor]
What happens when a capacitor is charged?
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.
How does a capacitor charge a battery?
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.
What happens when a capacitor is fully discharged?
As charge flows from one plate to the other through the resistor the charge is neutralised and so the current falls and the rate of decrease of potential difference also falls. Eventually the charge on the plates is zero and the current and potential difference are also zero - the capacitor is fully discharged.
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.
Can a capacitor be connected to a battery?
Consequently, ideally there is an open circuit there. If you connect the capacitor to a battery, as no current can flow, each plate would ideally inmediately acquire the same potential as the battery. You know that conductors ideally adquire the same potential all along them (in electrostatics).
What energy is needed to charge a capacitor?
Energy is needed from a power supply or other source to charge a capacitor. A charged capacitor can supply the energy needed to maintain the memory in a calculator or the current in a circuit when the supply voltage is too low. The amount of energy stored in a capacitor depends on:
