Answer 1

Answer:

electric potential.

Mark as Brainiest.

Answer 2

A charge is taken from a point A to point B. The work done per unit charge in this process is called potential difference.

• Moving a negligible test charge between two points yields the work per unit of charge, which is stated as the difference in electric potential between those sites.
• Electrochemical devices (electrochemical cells) or different metal junctions generating an electromotive force can be used to carry out the work. The work done by electric forces in transferring a charge from point A to point B is equal to the difference in electric potential difference.
