Question

What is Electrical Potential ? And who do the work to move positive charge from infinity to the electric field ? ​

Answer 1

The electric potential is the amount of work energy needed to move a unit of electric charge from a reference point to the specific point in an electric field with negligible acceleration of the test charge to avoid producing kinetic energy or radiation by test charge.

Amount of work done on a unit positive charge in an electric field from bringing it from infinity to certain point is called electric potential. Potential at infinity is assumed to be zero.

hope it helps

Answer 2

Answer:

The electric potential at any point in the electric field is defined as the work that must be done by the external force to move unit positive charge from infinity to that point without acceleration. The S.I. unit of potential difference is volt (V)
