A capacitor consists of two plates (foils ...) separated by an insulating medium. The insulating medium may be air, oil, a plastic film, and so on, and is known as the dielectric. The charge on the capacitor is actually stored by slightly distorting the molecules in the dielectric. The quality of a dielectric is measured by a factor known as K, and a higher K means that the molecule can store a larger distortion.
When we discharge the capacitor, the molecules are allowed to relax to their uncharged state.

What is dc link capacitor?
when the DC current flows through the capacitor .the leakage of the charges is in capacitor called Dc leakage capacitor .
What are the conditions of capacitor?
stores charges
What is the purpose of a capacitor in a circuit?
To store energy, in an electric field between separated charges. (An inductor stores energy in a magnetic field surrounding a current.)
How the charges on opposing plates of a capacitor compare?
In a capacitor, the charges on the opposing plates are equal in magnitude but opposite in sign. This means that if one plate has a positive charge, the other plate will have an equivalent negative charge. This separation of charge creates an electric field between the plates, allowing the capacitor to store electrical energy. The relationship between the charges and the capacitance is described by the formula ( Q = C \cdot V ), where ( Q ) is the charge, ( C ) is the capacitance, and ( V ) is the voltage across the plates.
What is capacitor function?
The capacitor is used to store the charge applied to it.This stored charge can be used to absorb voltage spikes and voltage drops.AnswerIt's a misconception that a capacitor stores charge. In fact, it stores energy. The net charge on a fully-charged capacitor is the same as on a fully discharged capacitor.
What is an electrolic capacitor?
An electrolytic capacitor uses an electrolyte (ions in a solution) to store charges.
What is the Meaning of electrolytic capacitor?
It means that 1) it is a capacitor, and 2) it uses an electrolyte to store the charges.
What device store charges on two parallel metal sheets?
A capacitor
How does a capacitor connected to a battery store and release electrical energy?
A capacitor connected to a battery stores electrical energy by accumulating opposite charges on its plates, creating an electric field. When the capacitor is connected to a circuit, it releases stored energy by allowing the charges to flow back through the circuit, creating an electric current.
What does not create charges but separate them?
A device that separates charges without creating new ones is a capacitor. Capacitors store energy in an electric field by collecting and holding positive and negative charges on separate plates, helping to store and release electrical energy when needed.
What happens to the current in a circuit as a capacitor charges?
What happens to the current in a circuit as a capacitor charges depends on the circuit. As a capacitor charges, the voltage drop across it increases. In a typical circuit with a constant voltage source and a resistor charging the capacitor, then the current in the circuit will decrease logarithmically over time as the capacitor charges, with the end result that the current is zero, and the voltage across the capacitor is the same as the voltage source.
Why does a capacitor stores a limited amount of energy?
A capacitor stores energy by accumulating opposite charges on its plates. However, it has a limited capacity based on its size and dielectric material. Once the capacitor reaches its maximum charge, it can no longer store additional energy.
What are the conditions of capacitor?
stores charges
What is dc link capacitor?
when the DC current flows through the capacitor .the leakage of the charges is in capacitor called Dc leakage capacitor .
What device separates positive and negative charges?
A device that can separate positive and negative charges is a capacitor. Capacitors store electrical energy by storing positive charges on one plate and negative charges on the other plate, creating an electric field between them.
Why capacitor charges exponentially why not linear?
because as the capacitor starts charging,the charges which are already built on capacitor opposes the further flow of charges. hence the process gets slow. thats we get sharp curve initially which gets flat further.
What is inductance and capacitance and impedence?
The inductance of an inductor is the capacity of the inductor to induce electric flux. The capacitance of a capacitor is the capacity of the capacitor to store charges. THE IMPEDANCE OF A CIRCUIT IS THE TOTAL OPPOSITION OFFERED TO THE FLOW OF ELECTRIC CURRENT.
