On inserting a dielectric between the plates of a capacitor, its capacitance is found to increase 5 times. What is the relative permittivity of the dielectric?

What is effect of dielectric on the capacitance of a capacitor?

Fill ups: A dielectric is used in a capacitor to ………………….its capacitance.

A parallel plate capacitor has a capacitance of 2muF . A slab of dielectric constant 5 is inserted between the plates and the capaitor is charged to 100 V and then isolated. What is the new potential difference, if the dielectric slab is removed?

Define dielectric constant of a medium in terms of capacitance of a capacitor.

A parallel plate capacitor has a capacitance of 2muF . A slab of dielectric constant 5 is inserted between the plates and the capaitor is charged to 100 V and then isolated. How much work is required to remove the dielectric slab?

A capacitor has some dielectric between its plates, and the capacitor is connected to a DC source. The battery is now disconnected and then the dielectric is removed. State whether the capacitance, the energy stored in it, electric field, charged stored and the voltage will increase, decrease or remains constant.

General instruction same as in chapter 1. Assertion: The electrostatic force between the plates of a charged isolated capacitro increases, when a dielectric fills whole space between the plates. Reason:The electric field between the plates of a charged isolated capacitor increases, when a dielectric fills the whole space between the plates.
