Potential is a measure of the energy required to drive current

between two electrodes.

In an electrochemical system,
Electrochemical System
potential may be either positive or negative, depending on the configuration. A positive potential indicates a spontaneous (also called galvanic) process, where current can be drawn from the system as redox

reactions occur. A negative potential indicates a non-spontaneous (also called electrolytic) process, where current must be applied to the system for redox reactions to occur.
