Solution

  1. Electric potential: The amount of work energy required to move a unit of electric charge from a reference point to a specific location in an electric field is known as the electric potential.
  2. Electric Potential, V=kqr where V is electric potential, k is coulomb constant k=8.98755×109kg·m3, q is the charge, and r is the distance of separation.
  3. Electric potential is represented by the symbol (V), which is also known as the voltage between two points. It's also defined as the joule per coulomb or the electromotive force (E.M.F).

1JC-1=1V

Where J is joules, C is the coulomb, and V is volt.

So, volt V is the SI unit of electric potential.
