Question

What is meant by saying that the potential difference between two points is 1 V?

Answer 1

Hey,

When 1 Joule of work is done to move a charge of amount 1 Coulomb from one place to another, then it is said that the potential difference between the two points is 1 Volt (V).

HOPE IT HELPS YOU:-))

Answer 2

When the one Joule of job is performed for moving the charge of amount 1 Coulomb exactly from one location to another location,  it is known that a potential difference between the two points is 1 Volt (V).

According the some studies, the potential at a particular point actually refers to particular work performed in giving the unit positive charge from infinity to that particular point.
