`C,Q,V` and `U` are capacitance, charge, potential difference and energy stored in an isolated parallel `1` plate capacitor respectively. Now a dielectric slab is placed between plates of capacitor, the quantities that decreases

C,V,U and Q are capacitance, potential difference, energy stored and charge of parallel plate capacitor respectively. The quantities that increase when a dielectric slab is introduced between the plates without discounting the battery are

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

A parallel plate capacitor is first charged and then a dielectric slab is introduced between the plates. The quantity that remains unchanged is
