electric charge

The state of any particle or body on which the there is an imbalance between electrons and protons. An excess of electrons causes a negative charge; a deficiency of electrons causes a positive charge. Electric charge, ELECTRIC FORCE and ELECTRIC POTENTIAL DIFFERENCE are fundamental to much of physiology.
