Uniform Electric Field (9 of 9) Separation Between Parallel Plates

Shows how to calculate the separation of parallel plates needed to achieve the desired electric field.

When two metallic plates are set a distance apart and then are attached to a potential difference, a battery for example, one plate will have a positive charge and the other plate will have a negative charge. The electric field will be directed away from the positive plate and toward the negative plate. The electric field between the plates is uniform throughout. That means the electric field strength is the same everywhere inside the parallel plates. Only at the ends of the plates will it show a non-uniform field. Such a system can be referred to as a parallel-plate capacitor.

Work must be done to move charges from one plate to another. The work can be done on the charged particle either by an external force or by the electric field. The work done on the particle will be equal to the potential energy given to the particle. Using the law of conservation of energy (initial potential energy = final kinetic energy) the velocity of the charged particles can be determined. The acceleration of the charged particle in the electric field can be calculated using newton's second law. Because there is a uniform electric field between the plates, the charged particle will experience uniform acceleration.
