In electronics and electrical engineering, the form factor of an alternating current waveform (signal) is the ratio of the RMS (root mean square) value to the average value (mathematical mean of absolute values of all points on the waveform). [1] It identifies the ratio of the direct current of equal power relative to the given alternating ...
Form factor is a hardware design aspect that defines and prescribes the size, shape, and other physical specifications of components, particularly in electronics. [ 1 ] [ 2 ] A form factor may represent a broad class of similarly sized components, or it may prescribe a specific standard.
Electrical conductivity: σ: Measure of a material's ability to conduct an electric current S/m L −3 M −1 T 3 I 2: scalar Electric potential: φ: Energy required to move a unit charge through an electric field from a reference point volt (V = J/C) L 2 M T −3 I −1: extensive, scalar Electrical resistance: R: Electric potential per unit ...
Form factor (quantum field theory), a semi-empirical formula used in effective quantum field theories; Atomic form factor, or atomic scattering factor, a measure of the amplitude of a wave scattered from an isolated atom; Electric form factor, the Fourier transform of electric charge distribution in space
IEC 60247 Insulating liquids – Measurement of relative permittivity, dielectric dissipation factor (tan d) and d.c. resistivity; IEC 60250 Recommended methods for the determination of the permittivity and dielectric dissipation factor of electrical insulating materials at power, audio and radio frequencies including metre wavelengths
The Small Form Factor with a 12 V connector (SFX12V) configuration has been optimized for small form factor (SFF) system layouts such as microATX. The low profile of the power supply fits easily into these systems.
In physics, the atomic form factor, or atomic scattering factor, is a measure of the scattering amplitude of a wave by an isolated atom. The atomic form factor depends on the type of scattering , which in turn depends on the nature of the incident radiation, typically X-ray , electron or neutron .
In certain business operations, taking a physical inventory is impossible or impractical. In such a situation, it is necessary to estimate the inventory cost. Two very popular methods are 1)- retail inventory method, and 2)- gross profit (or gross margin) method. The retail inventory method uses a cost to retail price ratio.
