Electrostatic potential

1. Electric potential due to uniformly charged spherical shell: Let us consider a spherical shell of radius R is charged by q. Calculate electric field at a point P, at a distance r from the centre of the shell. (i) If point P is outside the shell then potential at P is V = . […]

Concepts on electrostatic potential: 1. Electrostatic potential at a point on the axis of a uniformly charged ring: Let us consider a ring of radius R is uniformly charged by q. To calculate electrostatic potential at a point P on the axis of ring at a distance y from the centre O, we consider an

Electric potential at a point due to electric dipole: Let us consider an electric dipole consists of -q and +q at points A and B respectively separated by a distance 2a. O is the midpoint of the dipole and the dipole moment is = q2a. P is a point, at a distance r from O,

Electric potential: The electric potential at a point in the electric field due to a charge is the amount of work done to bring a unit positive charge (test charge) from infinity to that point against the electrostatics force of the electric field of source  charge. Units of electrostatic potential: C.G.S. unit: statvolt – If
