electrical energy- energy made available by the flow of electric charge through a conductor; "they built a car that runs on electricity" electricity alternating current,alternating electric current,AC- an electric current that reverses direction sinusoidally; "In the US most household current is AC ...
Once the potential field is computed (i.e. the PB equation is solved) it can be shown by a variational argument [17] that the total electrostatic energy ΔGest can be decomposed in the sum of three terms: (22)ΔGest=ΔGesfixed+ΔGesions+ΔGessol The first is the usual energy due...

Energy in physics is the ability to perform work. There are different types of energy, such as potential energy, kinetic energy, sound energy, and thermal energy.Answer and Explanation: The difference between potential and kinetic energy is that potential energy is stored energy and kinetic energy...
