Potential due to a point charge

The video tutorial explains how to determine the electrostatic potential at a point P due to a point charge Q located at the origin. It covers the calculation of work done in bringing a unit positive test charge from infinity to point P, emphasizing the positive work done against the repulsive force of a positive charge. The tutorial details the electrostatic force on the charge, the displacement, and the integration process to find the total work done. It also discusses the potential and field relationships, highlighting that the potential is inversely proportional to the distance and the field is inversely proportional to the square of the distance.
