How would you modify 5.0 nF parallel plate capacitor storing 25.0 J of energy so that it can store 50.0 J of energy without changing the charge on its plates?

In a parallel plate capacitor, how is the capacitance affected, when without changing the charge,area of the plate is halved.

In a parallel plate capacitor, how is the capacitance affected, when without changing the charge, the distance between the plates is doubled.

The plates of a parallel plate capacitor are 50m^2 and one mm apart apart when it is connected to a 45 V battery, what is the charge on either plate and the energy stored in it?

Show that during the charging of parallel plate capacitor,the rato of charging of a prallel plate capacitor,the rate of change of charge on each plate equals epsilon_0 times the rate of change of electric flux (phi_E) linked with it .What is the name given to the term epsilon_0 (dphi _E)/(dt) ?

you are given a 2 muF parallel capacitor. How would you establish an instantaneous displacement current in 1mA iin the space between its plates?
