In addition, the choice of copper salts in the copper complex was also discussed. In this work, a low-resistivity sintered copper film (7 × 10−6 Ω·m) at a temperature as low as 100 °C was achieved without using any reductive gas. Over the past decades, direct printing...

The resistivity of an exceedingly good electrical conductor, such as hard-drawn copper, at 20° C (68° F) is 1.77 × 10-8 ohm-metre, or 1.77 × 10-6 ohm-centimetre. At the other extreme, electrical insulators have resistivities in the range 1012 to 1020 ohm-metres. Britannica Quiz ...
Constantan is used for the measurement of temperature. It is used for the formation of thermocouples, along with the wires of other metals such as copper, iron, and chromel. It is especially used for resistance purposes since its resistance does not change much with the change in its temperat...
Resistivity or Coefficient of Resistance Resistivity or Coefficient of Resistance is a property of substance, due to which the substance offers opposition to the flow of current through it. Resistivity or Coefficient of Resistance of any substance can ea
