Question

Derive an expression for the energy stored a parallel plate capacitor. On charging a parallel plate capacitor to a potential v, the spacing between the plates is halved, and dialect medium of = 10 is introduced between the plates, without disconnecting the

d.C. Source. Explain, using suitable expressions, how the (i) capacitance, (ii) electric field and (iii) energy density of the capacitor change.
