unit electric field
1Electric field — In physics, the space surrounding an electric charge or in the presence of a time varying magnetic field has a property called an electric field (that can also be equated to electric flux density). This electric field exerts a force on other… …
2electric field — Elect. a vector quantity from which is determined the magnitude and direction of the force (electric force) on a charged particle due to the presence of other charged particles, accelerated charged particles, or time varying currents. Symbol: E… …
3electric field strength — noun the strength of an electric field at a given point, defined as the force exerted by the field on a unit electric charge at that point, in SI units measured in newtons per coulomb or volts per metre. Also, electric intensity …
4Electric charge — SI symbol: Q SI quantity dimension: Q SI unit: coulomb other units: e Derivations from other quantities: Q = I · …
5Field emission — (FE) is the emission of electrons from the surface of a condensed phase into another phase due to the presence of high electric fields. In this phenomenon, electrons with energies below the Fermi level tunnel through the potential barrier at the… …
6electric intensity — n the strength of an electric field at any point as measured by the force exerted upon a unit positive charge placed at that point * * * the force exerted on a unit charge at a point in an electric field. Symbol E. Called also electric field… …
7electric potential — 1. Also called potential. Elect. (at any point in an electric field) the work done per unit charge in moving an infinitesimal point charge from a common reference point to the given point. Symbol: V 2. Physiol. See action potential. [1870 75] * * …

9Electric motor — For other kinds of motors, see motor (disambiguation). For a railroad electric engine, see electric locomotive. Various electric motors. A 9 volt PP3 transistor battery is in the center foreground for size comparison. An electric motor converts… …
10electric dipole — Pair of equal and opposite electric charges, the centres of which do not coincide. An atom in which the centre of the negative cloud of electrons has been shifted slightly away from the nucleus by an external electric field is an induced electric …
