What does equivalent capacitance in general mean?

If the capacitors were in parallel then EC is defined as the capacitance of the capacitor to which for the same voltage as applied to the parallel capacitors then it stores the same total charge. But what does EC mean for a general circuit ie circuit consisting of capacitors in series and in parallel?

Capacitor Basics: How do Capacitors Work?

The fact that a capacitor needs some time to charge and discharge means that the shape of the output voltage can be delayed. The amount of delay is considered the phase shift, which may be further confused by the fact that it''s measured in degrees, which is basically a percentage of the full cycle of an alternating signal. ...

8.2: Capacitance and Capacitors

Multiple capacitors placed in series and/or parallel do not behave in the same manner as resistors. Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series.

What does the Voltage Rating on a Capacitor Mean?

The voltage rating is only the maximum voltage that a capacitor should be exposed to, not the voltage that the capacitor will charge up to. A capacitor will only charge to a specific voltage level if fed that level of voltage from a DC power source. Keep in mind that a good rule for choosing the voltage ratings for capacitors is not to choose ...

What does leakage of charge in plate and isolated spherical capacitors ...

Capacitor leakage occurs in several ways. First, if the insulation material that coats the outside of the capacitor is slightly conductive, it is possible for the excess electrons on one plate of the capacitor to slowly migrate to the opposite plate and slowly cancel the charge being held by the capacitor.

What are the behaviors of capacitors and inductors at time t=0?

Because capacitors store energy in the form of an electric field, they tend to act like small secondary-cell batteries, being able to store and release electrical energy.
