A parallel plate condenser is charged by connected it to a battery. Without disconnected the battery, the space between the plates is completely filled with a medium of dielectric constant `k`. Then

A parallel plate condenser is charged by connected it to a battery. The battery is disconnected and a glass slab is introduced between the plates. Then

An air capacitor is charged to a potential of 150 V and then the charging battery is disconnected. If the space between the plates is then completely filled with a material of dielectric constant 10 , then the potential between the plates will become

Two parallel plate capacitors of capacity C and 2C are connected in parallel and charged to a potential difference V. The battery is then disconnected and the space between the plates of the capacitor C is completely filled with a material of dielectic constant K. What is the final potential difference across the capacitors?
