What is the effect of inserting a dielectric other than air or vacuum between the plates of a capacitors?
Inserting a dielectric material between the plates of a capacitor increases the capacitance of the capacitor. The dielectric reduces the electric field between the plates and allows for more charge to be stored. This results in an increase in the amount of electric potential energy that can be stored in the capacitor.
What is stored inside a capacitor?
A capacitor stores electrical energy in the form of an electric field between two conductive plates separated by an insulating material called a dielectric.
How does the insertion of a dielectric affect the capacitance of a capacitor?
When a dielectric is inserted between the plates of a capacitor, it increases the capacitance of the capacitor. This is because the dielectric material reduces the electric field between the plates, allowing more charge to be stored on the plates for a given voltage.
What is the purpose of a dielectric in a capacitor?
Two functions - it provides electrical insulation, and it increases the capacitance, i.e., the amount of charge - and therefore also the amount of energy - that can be stored at a given voltage.
How can you calculate the energy stored in a capacitor?
The energy stored in a capacitor can be calculated using the formula: E 0.5 C V2, where E is the energy stored, C is the capacitance of the capacitor, and V is the voltage across the capacitor.

A capacitor is a device which stores energy by?
Magic. Look up capacitors on wikipedia!!A capacitor stores electrical charges in its plates.Both wrong. A capacitor stores energy as an electric field developed in the dielectric between its plates. A good dielectric with high permittivity (once called dielectric constant) concentrates this field, allowing more energy to be stored in a capacitor having the same plate area and separation but a dielectric of lower permittivity.

Can energy be stored in the form of electricity?
Yes. That's exactly the situation in the magnetic field of an inductor (coil),or in the dielectric of a capacitor. Both of those circuit elements are energy-storage devices.

The energy stored in a capacitor can be calculated using the formula: E 0.5 C V2, where E is the energy stored, C is the capacitance of the capacitor, and V is the voltage across the capacitor.

How to find the energy stored in a capacitor?
The energy stored in a capacitor can be found using the formula: E 0.5 C V2, where E is the energy stored, C is the capacitance of the capacitor, and V is the voltage across the capacitor.
What is the role of a dielectric in enhancing the capacitance of a parallel plate capacitor?
A dielectric in a parallel plate capacitor helps increase the capacitance by reducing the electric field strength between the plates, allowing more charge to be stored.
Where is energy stored in a capacitor and in inductor?
Energy is stored in a capacitor in the electric field between its plates. In an inductor, energy is stored in the magnetic field around the coil.
What is formula for maximum energy stored in capacitor?
The formula for maximum energy stored in a capacitor is given by ( E = \frac{1}{2}CV^2 ), where ( E ) is the energy stored, ( C ) is the capacitance of the capacitor, and ( V ) is the voltage across the capacitor.
