The proposition that the intensity of an electric field near the surface of a conductor is equal to the surface charge density on the nearby conductor surface divided by the absolute permittivity of the surrounding medium.

ELECTRIC IMAGE

A fictitious charge used in finding the electric field set up by fixed electric charges in the neighborhood of a conductor; the conductor, with its distribution of induced surface charges, is replaced by one or more of these fictitious charges. Also known as image. electric induction See electric displacement.

DEPLETION LAYER

An electric double layer formed at the surface of contact between a metal and a semiconductor having different work functions, because the mobile carrier charge density is insufficient to neutralize the fixed charge density of donors and acceptors. Also known as barrier layer (deprecated); blocking layer (deprecated); space-charge layer.

CONTACT ELECTRICITY

An electric charge at the surface of contact of two different materials. contact electromotive force See contact potential difference. contact gear ratio See contact ratio.

CHARGE DENSITY

The charge per unit area on a surface or per unit volume in space.

ELECTROSTATIC FORCE

Force on a charged particle due to an electrostatic field, equal to the electric field vector times the charge of the particle.

ELECTRIC POTENTIAL

The work which must be done against electric forces to bring a unit charge from a reference point to the point in question; the reference point is located at an infinite distance, or, for practical purposes, at the surface of the earth or some other large conductor. Also known as electrostatic potential; potential. Abbreviated V.

ELECTRIC DIPOLE MOMENT

A quantity characteristic of a charge distribution, equal to the vector sum over the electric charges of the product of the charge and the position vector of the charge.

COULOMB FIELD

The electric field created counterblow hammer forces they exert on one another.

MIRAGE

An optical phenomenon in which objects appear distorted, displaced (raised or lowered), magnified, multiplied, or inverted due to varying atmospheric refraction when a layer of air near the earth’s surface differs greatly in density from surrounding air.

HORIZONTALLY POLARIZED WAVE

A plane polarized electromagnetic wave in which the electric field vector is in a horizontal plane.
