Electrical energy has two dynamic components: voltage and current. Resistance is an inherent property of the materials through which energy stored as voltage causes the current to move.
Electric current is the term applied to the flow of an electric charge, usually in the form of electrons but possibly also moving ions in a liquid, gas, or plasma. Current is measured in units known as amperes , which are the number of coulombs of charge passing through a circuit reference point in one second of time. (A coulomb of ...
