a parallel plate capacitor is initially charged by battery and the battery is then dissconected. a dielectric slap is introduced between the plated .what changes would you expect in i)charge stored ii) electric field strength iii) capacitance iv) potential difference v ) energy stored vi) energy density

When battery across the plates of charged capacitor is disconnected and dielectric slab is introduced between the plates:
 
i) Charge remains constant.
ii) Electric field strength decreases.
iii) Capacitance increases.
iv) Potantial decreases.
v) Energy stored decreases.
vi) energy density decreases.
