1.(General Physics) the electrical property of a material that determines the resistance of a piece of given dimensions. It is equal toRA/l, whereRis the resistance,Athe cross-sectional area, andlthe length, and is the reciprocal of conductivity. It is measured in ohms. Symbol:ρFormer name...
where the symbol L indicates that the integration is taken over the whole half ring length. Using symmetry of the problem we can a priory write ∫L dFx=0. Therefore the whole force depends only on y-component dFy = dF cos α, where dF is the modulus of the force dF, dF = IBdl. ...
The diamond symbol represents the best experimental value for the two parameters as derived in the present work for random grain boundaries in polycrystalline Cu specimens. The open circles are the calculated values for specific individual CSL grain boundaries of various types in Cu [3]. The thin...
which persists to a wide temperature range without exhibiting saturation. As cooling down, those electron fluids lose the resistivity and condense into the superfluid. However, the origin of the linear-Tresistivity behavior and its

Errors of experimentally determined σ are below the symbol size. Table 4. Determined electrical conductivity of bulk material and (mostly) R1 as well as the penetration depth at 960 kHz (with 𝜎R1effσeffR1/) for CC57 and CC75. The major uncertainty of the calculation stems from the...
resistance is directly proportional to the length and temperature while it is inversely proportional to the cross-sectional area of the material. resistance is only proportional to the temperature of the conductor. it also depends on the nature of the material of the conductor. 3 symbol r ρ...
