Electric Field Due To A Uniformly Charged Infinite Plane Sheet

Definition of Electric Field. An electric field is defined as the electric force per unit charge. It is given as: E = F/Q. Where, E is the electric field; F is the force; Q is the charge; The variations in the magnetic field or the electric charges are the cause of electric fields. Volt per meter (V/m) is the SI unit of the electric field.

Capacitor

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone is a passive electronic component with two …

Fringing of electric field

How is the field produced? By charges on the surface. If you go to the quantum frame, it is excess electrons on one plate and excess positive charge (holes) on the other plate. Think of the electric field generated by an electron. It goes radially out. In an infinite plate capacitor the addition of the fields, because of symmetry becomes vertical.

Electric field in a parallel plate capacitor

The magnitude of the electric field due to an infinite thin flat sheet of charge is: Where ε 0 is the vacuum permittivity or electric constant. The charge density of each plate (with a surface area S) is given by: The electric field obeys the superposition principle; its value at any point of space is the sum of the electric fields in this point.

Electric Field, Flat Sheets of Charge

Electric Field: Parallel Plates. If oppositely charges parallel conducting plates are treated like infinite planes (neglecting fringing), then Gauss'' law can be used to calculate the electric field between the plates. Presuming the plates to be at equilibrium with zero electric field inside the conductors, then the result from a charged conducting surface can be used:

Electric field outside the plates of a capacitor

The electric field due to a plate of the capacitor is independent of the distance from it (its uniform) provided its not infinite. So if the finite identical plates have uniform charge density, away from the edges outside the capacitor the field should be 0.

17.4: The Electric Field Revisited

An electric field, like other fields (e.g., gravitational or magnetic), is a vector field that surrounds an object. Electric fields are found around electric charges and help determine the direction and magnitude of force the charge exerts on a nearby charged particle. It measures units of force exerted per unit of charge, and its SI units are N/C.
