  2. Form factor (electronics) - Wikipedia

    en.wikipedia.org/wiki/Form_factor_(electronics)

    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 ...

  3. Form factor (design) - Wikipedia

    en.wikipedia.org/wiki/Form_factor_(design)

    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.

    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.

  8. Atomic form factor - Wikipedia

    en.wikipedia.org/wiki/Atomic_form_factor

    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 .

  9. Inventory valuation - Wikipedia

    en.wikipedia.org/wiki/Inventory_valuation

    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.
