Voltage - Wikipedia
网页Voltage, also known as (electrical) potential difference, electric pressure, or electric tension is the difference in electric potential between two points. [1][2] In a static electric field, it corresponds to the work needed per unit of charge to move a positive test charge from the first point to the second point.
