A parallel plate capacitor consists of two parallel conducting plates separated by a dielectric, located at a small distance from each other. In a parallel plate capacitor, the electric field E is uniform and does not depend on the distance d between the plates, since the distance d is small compared to the dimensions of the plates.
Determining net force on a test charge As vector fields, electric fields exhibit properties typical of vectors and thus can be added to one another at any point of interest. Thus, given charges q 1, q 2,… q n, one can find their resultant force on a test charge at a certain point using vector addition: adding the component vectors in each direction and using the …
