In practice, capacitors deviate from the ideal capacitor equation in several aspects. Some of these, such as leakage current and parasitic effects are linear, or can be analyzed as nearly linear, and can be accounted for by adding virtual components to form an equivalent circuit. The usual methods of network analysis can then be applied. In other cases, such as with breakdown voltage, the effe

6 FAQs about [Where does the capacitor charge exist ]
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 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 much charge is stored when a capacitor is charged?
When a capacitor is charged, the amount of charge stored depends on: its capacitance: i.e. the greater the capacitance, the more charge is stored at a given voltage. KEY POINT - The capacitance of a capacitor, C, is defined as:
What happens when a voltage is applied across a capacitor?
When an electric potential difference (a voltage) is applied across the terminals of a capacitor, for example when a capacitor is connected across a battery, an electric field develops across the dielectric, causing a net positive charge to collect on one plate and net negative charge to collect on the other plate.
What happens when a capacitor is charging or discharging?
The time constant When a capacitor is charging or discharging, the amount of charge on the capacitor changes exponentially. The graphs in the diagram show how the charge on a capacitor changes with time when it is charging and discharging. Graphs showing the change of voltage with time are the same shape.
Do capacitor plates have a total charge?
As the capacitor plates have equal amounts of charge of the opposite sign, the total charge is actually zero. However, because the charges are separated they have energy and can do work when they are brought together. One farad is a very large value of capacitance.
