Gauss's law states that the enclosed electric charge in a closed surface is proportional to the net flux of an electric field through the surface. The Gauss's law is one of the Maxwell law of electromagnetism and it relates to the electric fields at points on the Gaussian (closed) surface and the net charge enclosed by that surface. The flux of the electric field passing through a closed surface is defined as the product of the electric field passing through the area and the area of the surface in a plane perpendicular to the field. In other words, Gauss law is also defined as the total charge Q enclosed within a surface divided by dielectric constant. Hence, Gauss law can be mathematically written as, ? = Q /?0 Where, ? = Electric flux through a given surface, Q = total charge within a given surface, ?0 = Electric constant. read less

Just be careful gauss law is valid for moving charge but coulomb is not.

When two plate of different charge are placed near each other, the two E-fields between the plates add while the E-field outside the plate cancel When the plates are close to each other to form a capacitor, the E-field between the plates is constant through out the interior of the capacitor as long as one is not near the edges of the plates. Since the electric field is the negative of the gradient of the potential and the E-field is constant inside a capacitor, the magnitude of the Electric field has a very simple relation to the voltage between the plates and their separation d. This relationship is also true in an electrical wire were V is the voltage across the ends of the wire and d is the length of the wire. Using the definition of capacitance we can determine the capacitance C of an ideal capacitor as a function of its structure. This equation for the capacitance of a parallel capacitor shows that C is a constant independent of the charge stored in on the plates or the voltage across the capacitor. By placing a thin insulating material (a dielectric) between the plates the separation d can be reduced thus increasing the capacitance of the capacitor and prevent the plates from touching. It takes more voltage to store the same amount of charge on a capacitor because of the presence of the dielectric. Typically a dielectric contains polar molecules which partially line up in the presence of the electric field. The dielectric creates an E-field in the opposite direction which reduces the overall E-field between the plates. read less

In electricity, a corona discharge is an electrical discharge brought on by the ionization of a fluid surrounding a conductor that is electrically energized. The discharge will occur when the strength (potential gradient) of the electric field around the conductor is high enough to form a conductive region, but not high enough to cause electrical breakdown or arcing to nearby objects. It is often seen as a bluish (or other color) glow in the air adjacent to pointed metal conductors carrying high voltages. Spontaneous corona discharges are undesirable where they waste power in high-voltage systems or where the high chemical activity in a corona discharge creates objectionable or hazardous compounds, such as ozone. Controlled corona discharges are used in a variety of filtration, printing and other processes. read less

1.parallel plate capacitors are two metal surfaces placed parallel and provide some electric energy to create some potential difference to store the energy in form of electrostatic.this energy can not dissipate with out providing any external load. 2.Equipotential surfaces are the surfaces having zero potential difference between two points on their surfaces. 3.0.5CV^2 5.gauss theorem denotes change enclosed by the closed surface having some volume is always equals to charge floated on that surface. you know in conductor electric intensity become zero it is always on the surface and out ward normal direction to that surface.... these are all up to my knowledge only i didn't just copy paste. Thank You. read less

Actually there is no clear line of demarcation between these two terms, but nowadays Ionisation Energy is preferably used.
