Resistivity Log In subject area: Engineering The resistivity log, often referred to as an “electric” log, operates on the basis of formation response to an imposed electric current and the natural resistance of fluids in various rock layers. From: Well Integrity for Workovers and Recompletions...
ρ = resistivity of the conductor material (ohm metre, Ω m) L = length of conductor (m) A = cross-sectional area of conductor (m2) Resistivity of some Common Conductors Aluminum: 2.65×10-8Ω m (0.0265 μΩ m) Carbon: 10×10-8Ω m (0.10 μΩ m) Copper: 1.724×10-8Ω...
What is the resistivity of the wire when a 0.82 {eq}\displaystyle{ \Omega }{/eq} of uniform copper wire is 15 m long and 2.5 mm thick in diameter? Resistivity: Resistivity is the intrinsic property of a material that has a corresponding extri...
In the first step of the testing process, a one-inch by one-inch graphite-filled test sample was cut. The sample was placed between the two copper test electrodes. Figure 3 shows the test cell on the standard platens of the bench press. ...
The resistivity of aluminum is 2.75 x 10^-8 Ohm m and the resistivity of copper is 1.69 x 10^-8 Ohmm. An aluminum wire with a cross-sectional area of 6.8\times 10^{-6} m^2 carries a current of 2.8 A.\ Find...
To this end, several attempts have been made at providing stable, high resistivity films and coatings. Early attempts involved sputter deposition of tantalum nitride, copper-germanium alloys and Nichrome (an alloy containing nickel, chromium and iron; "Nichrome" is a trademark of Driver-Harris Co....
The present invention relates to the production of a grain oriented electrical steel composition having a volume resistivity of at least 50 micro-ohm-cm. The melt composition of the steel consists ess
Two other ground schemes were tested. One scheme was through-the-paint capacitive grounding using 3"×3" thin pads of copper tape at the top and bottom of the antenna. The second ground scheme used horizontal on-glass 3" wide copper strips 49. The latter scheme is operationally more attract...
