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 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.


When a dielectric is inserted in to the plates which quantity remain same?

The capacitance of the capacitor remains the same when a dielectric material is inserted between the plates. However, the electric field between the plates decreases due to the polarization of the dielectric material, which increases the capacitance of the capacitor.


What is the effect of a dielectric material on the electric field of a capacitor?

A dielectric material placed between the plates of a capacitor reduces the electric field strength within the capacitor, increasing its capacitance. This is because the dielectric material polarizes in response to the electric field, creating an opposing electric field that weakens the overall field between the plates.


What is the effect of a dielectric on the energy stored in a capacitor?

A dielectric increases the energy stored in a capacitor by reducing the electric field strength between the plates, allowing for more charge to be stored at a lower voltage.


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.

How do capacitors classified?

capacitors are classified on the basis of dielectric material used inside it. For example the electrolytic capacitor consist electrolyte as dielectric mica capacitor consist mica as dielectric between plates and ceramic capacitor consist ceramic as dielectric.


What is the material use in the capacitor?

Capacitors are named after their dielectrics. So, an 'air capacitor' uses air as its dielectric, a 'mica capacitor' uses mica as its dielectric, and so on. There are lots of different dielectric used to separate the plates of a capacitor, each with different permittivities and dielectric strengths. As the perfect dielectric (i.e. one with both a very high permittivity and a very high dielectric strength) doesn't occur, the choice of dielectric is always a compromise between it permittivity and dielectric strength.


If you take out the battery in a capacitor before inserting a dielectric will there still be charge on the dielectric?

The charge in a capacitor is between the plates. The dielectric is only an insulator that allows the plates to be very close without touching and discharging the charge. There is no battery in a capacitor.

What type of capacitor uses aluminum as its dielectric?

Electrolytic capacitors use aluminium as a dielectric.


What is the element of a capacitor?

The element of a capacitor is a dielectric material, which is the insulating layer between the two conductive plates. This dielectric material helps store electrical energy by preventing the plates from touching and forming a short circuit.


What happens to the charge of a capacitor when a dielectric slab is fit in it?

Changing the dielectric causes the capacitance to change.

How does a capacitor discharge if there is dielectric material separating the two plates?

The capacitor can discharge over the connecting wires; i.e., outside the capacitor. Some discharge can also occur over the dielectric, since it will not insulate completely.
