    A single in line (SIL) resistor package with 8 individual 47 ohm resistors. This package is also known as a SIP-9. One end of each resistor is connected to a separate pin and the other ends are all connected together to the remaining (common) pin – pin 1, at the end identified by the white dot.

    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.

    The SI unit of electrical resistivity is the ohm-metre (Ω⋅m). [ 1 ] [ 2 ] [ 3 ] For example, if a 1 m 3 solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is 1 Ω , then the resistivity of the material is 1 Ω⋅m .

    Also called chordal or DC resistance This corresponds to the usual definition of resistance; the voltage divided by the current R s t a t i c = V I. {\displaystyle R_{\mathrm {static} }={V \over I}.} It is the slope of the line (chord) from the origin through the point on the curve. Static resistance determines the power dissipation in an electrical component. Points on the current–voltage ...

  6. Siemens (unit) - Wikipedia

    en.wikipedia.org/wiki/Siemens_(unit)

    The siemens (symbol: S) is the unit of electric conductance, electric susceptance, and electric admittance in the International System of Units (SI). Conductance, susceptance, and admittance are the reciprocals of resistance, reactance, and impedance respectively; hence one siemens is equal to the reciprocal of one ohm (Ω −1) and is also referred to as the mho.

  7. Ohm - Wikipedia

    en.wikipedia.org/wiki/Ohm

    The unit was based upon the ohm equal to 10 9 units of resistance of the C.G.S. system of electromagnetic units. The international ohm is represented by the resistance offered to an unvarying electric current in a mercury column of constant cross-sectional area 106.3 cm long of mass 14.4521 grams and 0 °C.
