In a parallel plate capacitor, the capacitance

When dielectric is inserted in the space between plates of a capacitor, then

A dielectric slab is placed between the plates of a parallel plate capacitor. Its capacitance

When a dielectric is inserted in the space between parallel plates of a charged capacitor, then

By inserting a plate of dielectric material between the plates of a parallel plate capacitor at constant potential, the energy is increased five times. The dielectric constant of the material is

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.

A parallel plate capacitor of capacitance 200muF is connected to a battery of 200 V. A dielectric slab of dielectric 2 is now inserted into the space between plates of capacitor while the battery remain connected .The change in the electrostatic energy in the capacitor will be __________J.

A sheet of copper is inserted in the air gap of a parallel plate capacitor, without touching any of the two plates of the capacitor. The capacitance of the capacitor is

Two capacitors are connected in parallel to a battery. If a dielectric medium is inserted between the plates of one of the capacitors then the enegry stored in the system will increase. On inserting dielectric medium between the plates of a capacitors, its capacity increases.

Assertion: Id distance between the parallel plates of a capacitor is halved, then its capacitance is doubled. Reason: The capacitance depends on the introduced dielectric.
