Hey
Here is Ur answer

A positive potential means that the charge of the influencial particle is the same as the charge of the influenced particle. Since like charges repel, work has to be done against the coulombic forces between the charges to bring them closer.
A negative potential means that the charge of the influential particle is the opposite of the influenced particle. Since unlike charges attract, they wouldn't need external work to bring them closer. _________________________________________________________

The electrostatic potential is always specified with respect to some arbitrary reference point. That is because only differences in electrostatic potential matter physically.
So, a positive electrostatic potential at some point means that a positive (negative) charge at that point will have a higher (lower) potential energy compared to the reference point.
Just as the electric field is described as force per unit charge, electric potential at a point can be described as electrical potential energy per unit charge. This concept is useful in calculations involving energies of charged particles. Not only that, as force is related to work, electric potential is closely related to the electric field .
Potential being a scalar quantity, it is easy to deal with, than electric field. Hence, when we need to determine an electric field, it is easy to find the potential first and find the field from it.
The electrostatic potential at any point in an electric field is defined as the work done in bringing a unit positive charge from infinity to that point against the electric force of the field.
V = W/q
where V is the potential
W is work done
q the charge
S.I. unit is Joule/Coulomb = 1 Volt
Thanks.
