Testing method for conductor-resistance and resistivity of metallic resistance materialsdoi:JIS C 2525:1999
The Fourth Law states that “the conducting material depends on its temperature”. According to this law when the temperature of a metallic conductor is increased, it’s value also increases. From the first, second and third law, the resistance of a material can be given asR ∝ L/A i.e ...
Joseph Priest, in Encyclopedia of Energy, 2004 6.1.1 Platinum Resistance Temperature Detector The resistance to the flow of electric charge in a conductor depends on temperature. For metals, the resistance increases as the temperature increases. The algebraic relation between temperature and resistance ...
The electrical resistivity (R) of a material is given by R = δL/A, where δ is the bulk resistivity in ohm-centimeters (Ω-cm), L is the length of the conductor in cm, and A is the cross-sectional area of the conductor in cm2. ...
but where microscopic recesses occur on a surface it is likely that a gap will be created between it and the other surface. This gap increases the electrical constriction resistance of the contacting surfaces because the medium in the gap (typically air) is a poorer conductor of electricity than...
Over 30 years of Wires and Cables manufacture experience and Export to over 50 countries. 1. Applications: Enamelled wire is a metallic conductor insulated with a varnish and generally used for electrical applications. Most times enamelled wire is wound in...
A two-line transmission line terminated at both ends by resistors is investigated to see how the signal depends on the line's shunt conductance and the ter... KS Yee 被引量: 0发表: 1971年 Cultivar Differences in Resistance to the Inhibitory Effects of Near-UV Radiation among Asian Ecotype ...
a single conducting element in the profiler support cable. The outer cable sheath acted as both mechanical support and the return conductor. This data transfer method has subsequently been used on most electronic profiling systems, despite the ever-present concern for possible ground-fault problems. ...
The d.c. orohmic resistanceof linear resistors (a category confined principally to metallic conductors) is a function of the dimensions of the conducting path and of theresistivityof the material from which the conductor is made. A wire of lengthl, cross-sectionaand resistivity ρ has, at co...
