Relationship Between Electric Field and Electric Potential
The potential at any point in space due to a point charge is the work done by an external force in bringing a positive unit test charge from an infinitely distant point to that point
Electric Potential Due to a Point Charge
The net electric field produced by a number of point charges is simply the vector sum of the individual electric fields that each object would create in the absence of the others
