A capacitor consists of two separated conductors and its capacitance C represents its "capacity to store charge". Applying a voltage difference V between these two conductors can induce charge +Q on one conductor and Q on the other conductor (so the total charge is zero, that is, the capacitor as a whole is charge neutral), such that:

Regelation is the phenomenon in which pressure is used to melt ice into water under 0 degree celsius. Once the pressure from ice is removed, the melted water freezes back to ice. This phenomenon has been showcased by a number of individuals through circling a fine wire around a square block of ice and applying pressure onto it with a heavyweight.
This is the principle of a capacitor. A typical capacitor which is a parallel plate capacitor is made up of two parallel plates which are separated by a distance d. A is the area of cross section of these plates and if +Q charge is given to one plate there will be -Q charge on the other plate. How do we charge this kind of a capacitor?
