WebApr 9, 2024 · I have measured the resistivity of a nichrome ($80$ Nickel $20$ Chrome) wire as a function of temperature. Because my setup is quite crude (just a power supply and a couple of multimeters to measure voltage and current), I do not know if the bump that I get around $0.6A$ is physical or an artifact of the measuring setup. WebData Sheet: Nickel-Chromium Alloys. These alloys are especially characterized by high resistivity and high resistance to oxidation and chemical corrosion. They are suitable for making high-value electrical resistors, heating wires, heating cords and cables. NiCr 80:20 is suitable for heating elements used for temperatures upto 1200°C.

WebTranscribed image text: Problem 2.1 : A 15 kW, 220 V single phase resistance oven employs nickle-chrome wire for its heating elements. If the wire temperature is not to exceed 1000 °C and the temperature of the charge is to be 600 °C, calculate the diameter and length of the wire. Assume radiating efficiency to be 0:6 and emissivity as 0.9.

WebResistivity = (Resistance * Area ) / Length. So the resistance for both the wires is supposed to be same , and ratio of diameters is given , from which you can deduce the ratio of Areas of the two wires and the values of the resistivity for both wires is given. WebProperties [ edit] Nichrome is consistently silvery-grey in colour, is corrosion-resistant, has a high melting point of about 1,400 °C (2,550 °F ), and has an electrical resistivity of around 112 μΩ–cm, which is around 66 times higher resistivity than copper of 1.678 μΩ–cm.
