Derive a relation for capacitance of a parallel plate capacitor with dielectric slab of thickness t filled between the plates. Or. Write expression for capacitance of a parallel plate capacitor and explain the effect of dielectrics on capacitance.

The capacity of a parallel plate capacitor with air is 18 pF. When a dielectric material is inserted in the space between the plates, its capacity becomes 108 pF. Calculate the permittivity of the material. What is the material?

Parallel Plate Capacitors with and without Dielectric

The space between the plates orf a parallel plate capacitor is completely filled with a meterail of resistaivity 2xx10^(11) Omegam and dielectric constant 6. Capacity of the capacitor with the given dielectric medium between the paltes is 20uF. Find the leakage current if a potential difference 2500 V is applied across the capacitor.

A dielectric is inserted between the plates of an isolated fully-charged capacitor. The dielectric completely fills the space between the plates. The magnitude of electrostatic force on either metal plate decreases, as it was before the insertion of dielectric medium. Due to insertion of dielectric slab in an isolated parallel plate capacitor (the dielectric completely fills the space between the plates), the electrostatic potential energy of the capacitor decreases.

The capacities of a parallel plate capacitor first with air and then on introducing oil between its plates are 50muF and 120muF respectively. The dielectric constant of oil is

A parallel plate capacitor is filled with dielectrics. What is capacitance?
