- Definition of Electric Field
- The electric field at any point
- Electric Field Lines
- provide a means for visualizing the directions and the magnitudes of electric fields
- Field due to a Charged Disk
- The electric field magnitude at a point on the central axis through a uniformly charged disk is given by
- Field due to a Point Charge
- The magnitude of the electric field E set up by a point charge q at a distance r from the charge is
- Field due to an Electric Dipole
- The magnitude of the electric field set up by the dipole at a distant point on the dipole axis is
- Force on a Point Charge in an Electric Field
- When a point charge q is placed in an external electric field E
- Dipole in an Electric Field
- The electric field exerts a torque on a dipole
- The dipole has a potential energy U associated with its orientation in the field
