Webvolt per meter (V/m): The standard unit of electric field (E-field) strength is the volt per meter (V/m). An E field of 1 V/m is represented by a potential difference of 1 V existing between two points that are 1 m apart. Reduced to base SI units, 1 V/m is the equivalent of one meter kilogram per second cubed per ampere (m ? kg ? s -3 ? A -1 ). WebThere are two principal methods by which a dielectric can be polarized: stretching and rotation. Stretching an atom or molecule results in an induced dipole moment added to every atom or molecule. Magnify Rotation occurs only in polar molecules — those with a permanent dipole moment like the water molecule shown in the diagram below. Magnify WebThe dielectric strength of an elastomer is the voltage required to puncture a sample of known thickness and is expressed as volts per mil of thickness. The rate of voltage application, the geometry of the electrodes, and the shape of the test specimen influence the results obtained.
