    As quoted in an online version of: David R. Lide (ed), CRC Handbook of Chemistry and Physics, 84th Edition.CRC Press. Boca Raton, Florida, 2003; Section 4, Properties of the Elements and Inorganic Compounds; Physical Properties of the Rare Earth Metals

  3. List of resistors - Wikipedia

    en.wikipedia.org/wiki/List_of_resistors

    A resistance decade box or resistor substitution box is a unit containing resistors of many values, with one or more mechanical switches which allow any one of various discrete resistances offered by the box to be dialed in. Usually the resistance is accurate to high precision, ranging from laboratory/calibration grade accuracy of 20 parts per ...

    en.wikipedia.org/wiki/Electrical_resistivity_and...

    The resistivity can be expressed using the SI unit ohm metre (Ω⋅m) — i.e. ohms multiplied by square metres (for the cross-sectional area) then divided by metres (for the length). Both resistance and resistivity describe how difficult it is to make electrical current flow through a material, but unlike resistance, resistivity is an ...

    For example, a 10 ohm resistor connected in parallel with a 5 ohm resistor and a 15 ohm resistor produces ⁠ 1 / 1/10 + 1/5 + 1/15 ⁠ ohms of resistance, or ⁠ 30 / 11 ⁠ = 2.727 ohms. A resistor network that is a combination of parallel and series connections can be broken up into smaller parts that are either one or the other.

  6. Ohm - Wikipedia

    en.wikipedia.org/wiki/Ohm

    One of the functions of many types of multimeters is the measurement of resistance in ohms.. The ohm is defined as an electrical resistance between two points of a conductor when a constant potential difference of one volt (V), applied to these points, produces in the conductor a current of one ampere (A), the conductor not being the seat of any electromotive force.

    is a reference (standard) resistance value. The Steinhart–Hart equation assumes is 1 ohm. The curve fit is much less accurate when it is assumed = and a different value of such as 1 kΩ is used. However, using the full set of coefficients avoids this problem as it simply results in shifted parameters.

  9. RKM code - Wikipedia

    en.wikipedia.org/wiki/RKM_code

    For brevity, the notation omits to always specify the unit (ohm or farad) explicitly and instead relies on implicit knowledge raised from the usage of specific letters either only for resistors or for capacitors, [nb 1] the case used (uppercase letters are typically used for resistors, lowercase letters for capacitors), [nb 2] a part's appearance, and the context.
