Voltage:
Voltage, electric
potential difference, electric pressure or electric tension is
the difference in electric potential between two points, which (in a
static electric field) is defined as the work needed per unit of
charge to move a test charge between the two points. In the International
System of Units, the derived unit for voltage (potential difference)
is named volt.
