Electric field in a cylindrical capacitor
In this page we are going to calculate the electric field in a cylindrical capacitor. A cylindrical capacitor consists of two cylindrical concentric plates of radius R 1 and R 2 respectively as seen in the next figure. The charge of the internal plate is +q and the charge of the external plate is –q. ...

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 …

The Direction of the Field. Equation 5.4 enables us to determine the magnitude of the electric field, but we need the direction also. We use the convention that the direction of any electric field vector is the same as the direction of the electric force vector that the field would apply to a positive test charge placed in that field.
