Question

What is the difference between electric potential and electric potential difference?

Answer 1

Difference between electric potential and electric potential difference:

Electric potential	Electrical Potential difference
Electric potential is the amount of work required to move a point charge from a reference point (infinity) to a specific point against the electric field.	Electrical potential difference is the difference in electric potential between two points.
The concept of electric potential is useful in understanding electrical phenomena.	Electric potential difference is defined as the work done per unit of charge in moving a test charge between two points.
Electric potential is measured as work done per charge.	Potential difference can be measured by voltmeter connected parallel to the instrument to be measured.
