Existing and ready for action but not yet active; possible.
1. Physics. The amount of energy per unit charge needed to move a charged particle from a reference point to a designated point in a static electric field. The electrical potential difference between two points is called electric voltage.
2. Biophysics. The bioelectric potential is the varying electric potential which accompanies all biochemical processes (e.g., action potential or membrane potential), as those manifested in the ECG and EEG.
