If current doesn''t flow in an open circuit, how are capacitors charged?
Well though there is no electric charge flowing between the plates of the capacitor, there is the infamous displacement current, that is a "virtual" current that corresponds to the rate of change of electric field between the plates of the capacitors as the capacitor is charging. Ofcourse it turns out that it isn''t virtual at all in the sense that a time-changing electric field

6 FAQs about [Can ordinary capacitors store electricity ]
How much energy can a capacitor store?
A: Capacitors can store a relatively small amount of energy compared to batteries. However, they can charge and discharge energy rapidly, making them useful in applications that require rapid energy storage and release. Q: How much time a capacitor can store energy?
Do capacitors store more energy than batteries?
A: In general, capacitors store less energy than batteries. Batteries have a higher energy density, meaning they can store more energy per unit volume or mass. Capacitors can charge and discharge energy rapidly but have a lower overall energy storage capacity.
How do you increase the energy a capacitor will store?
To increase the energy a capacitor will store, you can either use a better material for the dielectric or use bigger metal plates. To store a significant amount of energy, you'd need to use absolutely whopping plates.
Does a capacitor store energy on a plate?
A: Capacitors do store charge on their plates, but the net charge is zero, as the positive and negative charges on the plates are equal and opposite. The energy stored in a capacitor is due to the electric field created by the separation of these charges. Q: Why is energy stored in a capacitor half?
How does capacitance affect energy stored in a capacitor?
Capacitance: The higher the capacitance, the more energy a capacitor can store. Capacitance depends on the surface area of the conductive plates, the distance between the plates, and the properties of the dielectric material. Voltage: The energy stored in a capacitor increases with the square of the voltage applied.
