This suburb of ours used to be a village, and because some of the people slurred the name and pronounced it Holliwell, many a minor poet indulged in fancies about a Holy Well, with spells and fairies and all the rest of it, filling the suburban drawing-rooms with the Celtic twilight.
The Superposition Principle states that net electric field produced at any point by a system of charges is equal to the vector sum of all individual fields, produced by each charge at this point.where n is total number of charges in the system.The Superposition Principle for two point charges.he Superposition Principle states that net electric field produced at any point by a system of charges is equal to the vector sum of all individual fields, produced by each charge at this point.
Electric potential is actually defined as the NEGATIVE potential function of electric field (not the vector calculus potential function, but its negative), as is any concept of potential in physics, in order that we can think of it as a form of energy. This means that electric field is the negative gradient of electric potential. If you've never heard of the term gradient, all it means is a vector of derivatives of a scalar function of space, each component of which is a derivative of this function relative to the respective direction in the coordinate system.
