Resistivity — Electrical resistivity (also known as specific electrical resistance) is a measure of how strongly a material opposes the flow of electric current. A low resistivity indicates a material that readily allows the movement of electrical charge. The… … Wikipedia
Electrical resistivity and conductivity — This article is about electrical conductivity in general. For the specific conductance of aqueous solutions, see Conductivity (electrolytic). For other types of conductivity, see Conductivity. Electrical resistivity (also known as resistivity,… … Wikipedia
Negative temperature coefficient — A negative temperature coefficient (NTC) occurs when the thermal conductivity of a material rises with increasing temperature, typically in a defined temperature range. For most materials, the thermal conductivity will decrease with increasing… … Wikipedia
Temperature coefficient — The temperature coefficient is the relative change of a physical property when the temperature is changed by 1 K. In the following formula, let R be the physical property to be measured and T be the temperature at which the property is… … Wikipedia
Manganin — is a trademarked name for an alloy of typically 86% copper, 12% manganese, and 2% nickel. It was first developed by Edward Weston in 1892, improving upon his Constantan (1887). Manganin foil and wire is used in the manufacture of resistors,… … Wikipedia
