Capacitance is analogous to the capacitance of water tank at our home. larger the size of tank, larger will be its capacitance despite the presence of water in tank or empty. An empty tank or water filled tank has same capacitance. similarly, whether the capacitor is charged or not charged its capacitance is always fixed.
Inserting a dielectric slab between the plates of a parallel plate capacitor increases its capacitance. The dielectric material reduces the electric field strength for the same amount of charge, allowing the capacitor to store more charge at the same voltage. The increase in capacitance depends on the dielectric constant of the material.

The amount of electrical energy a capacitor can store depends on its capacitance. The capacitance of a capacitor is a bit like the size of a bucket: the bigger the bucket, the more water it can store; the bigger the capacitance, the more electricity a capacitor can store.
