Question

What is potential Difference ?​

Answer 1

Potential Difference - The difference in electric potential between two points in an electric field; the work that has to be done in transferring unit positive charge from one point to the other, measured in volts.

The work done is measured in joules and charge in coulombs, the unit of electric potential is joules /coulombs, the unit of electric potential is joules/coulomb or volts.

Hope it helps!

Answer 2

Answer:

Voltage, electric potential difference, electric pressure or electric tension is the difference in electric potential between two points. The difference in electric potential between two points in a static electric field is defined as the work needed per unit of charge to move a test charge between the two points.
