# Electric potential And potential difference

I'm studying the electrostatics, then i read the concept of electric potential and potential difference. They said "the electric potential at a point in the given electric field is defined as the work done in moving per unit positive charge from infinity to that point against electrostatic forces of attraction of the source charge irrespective of path followed." I did not understand what is this work done from infinity and concept of potential difference. Clearly saying i did not understand both concepts of potential difference and electric potential? Please clear my concepts and tell me what is this work done?
